Free, Open-Source, and Proprietary Software Explained
BSD, Linux, Unix, and Independent Distributions Today
Real-World Examples Around the Globe
Conclusion
In our digital age, software underpins almost every gadget and service we use – from smartphones and laptops to cloud servers and smart TVs. But not all software is the same. There are free software and open-source communities that champion user freedoms, and there are proprietary (closed-source) vendors that keep code under tight control. Understanding the differences can feel like navigating a complex terrain, but it’s easier when we see the whole panorama. This article will guide you through the history, principles, and real-world landscape of free/open-source and proprietary software. We’ll cover familiar names like Linux, BSD, and Unix, and look at how individuals, companies, and even governments around the world are choosing between these models.
Free and open-source software (often grouped as FOSS or FLOSS) is defined by licensing that guarantees users the rights to use, study, modify, and share the software freely ¹. These rights trace back to Richard Stallman’s 1980s free software movement: Stallman founded the GNU Project and the Free Software Foundation in 1985 to defend what he called the “Four Essential Freedoms” of software use ². In practice this meant writing the GNU General Public License (GPL), which ensures any distributed software grants those freedoms to the user. In the 1990s, thinkers like Eric S. Raymond and Bruce Perens coined the term open source to describe essentially the same model from a pragmatic angle (focusing on collaborative development and practical benefits). Today, “free software” and “open-source software” largely overlap: both require source code to be available. In contrast, proprietary software is licensed restrictively (or keeps source code secret) – examples include operating systems like Windows or many commercial applications. In short, FOSS champions user empowerment and community, while proprietary software often emphasizes commercial control and patent/license protection.
Free, Open-Source, and Proprietary Software Explained
Free Software – Stallman’s vision – insists on user freedom. According to the Free Software Foundation (FSF)¹², free software is defined by the right to run the program, to study/modify it, to redistribute copies, and to distribute modified versions. In other words, users must have full access to the source code and the license cannot restrict any of those uses ¹. The FSF famously distinguishes this from “open source” only in philosophy: free software is a moral right of the user, whereas open-source stresses pragmatic benefits (like reliability and innovation).
Open-Source Software – as defined by the Open Source Initiative¹³ – shares the same practical terms (source code available, allowed to modify and share) but with a looser emphasis on ideology. In 1998, developers like Eric Raymond argued that marketing “open source” was more business-friendly than “free software” (which some misinterpret as “no cost”). The Open Source Definition lists criteria (10 points) but essentially any OSI-approved license must allow free use, modification, and distribution of code. Famous open-source licenses include GPL (copyleft), MIT, Apache, and BSD variants.
Proprietary (Closed-Source) Software – by contrast – typically does not provide source code or rights to modify. It is often sold or licensed under conditions that forbid sharing or alteration. Classic examples are Microsoft Office, Adobe Photoshop, or device firmware. Proprietary software ¹⁴ can be highly polished and widely supported, but users are at the mercy of the vendor for fixes, updates, and compatibility. The Wikipedia definition of FOSS says it is “the opposite of proprietary software, which is licensed restrictively or has undisclosed source code.” ¹.
The net result is that FOSS enables anyone (individuals, companies, governments) to inspect and adapt the software to their needs. In contrast, proprietary software can lock users into a single vendor’s ecosystem. Over time, many have argued that FOSS often leads to lower costs, higher security, and more innovation, since problems are fixed by a global community. Indeed, advocates cite examples like the free Linux operating system (originally kernel by Linus Torvalds in 1991) and the thousands of open-source projects on GitHub as proof of this thriving model. Proprietary vendors, on the other hand, invest heavily in polished experiences and exclusive features, and they control licensing revenue. The two worlds coexist: a computer user might run a Linux (open-source) server but also use Microsoft Office (proprietary) on their desktop, for instance. The choice often comes down to specific needs, philosophies, and budgets.
BSD, Linux, Unix, and Independent Distributions Today
The operating system landscape exemplifies these models in action. Linux (the kernel plus GNU tools, often called GNU/Linux) is a free/open platform developed by thousands of contributors worldwide. There are hundreds of Linux distributions (“distros”) – Debian, Ubuntu, Fedora, Red Hat Enterprise Linux, Arch, SUSE, Mint, CentOS, and many more – each putting a different spin on how Linux is packaged, updated, and supported. As of 2024, over 600 active Linux distributions exist, with Ubuntu alone used on roughly a third of them ⁷. Many businesses and enthusiasts choose Linux because it is stable, secure, and highly customizable. For example, Ubuntu has become popular for both personal use and corporate servers, Fedora/Red Hat are staples in enterprise data centers, and Arch or Gentoo appeal to power users for tinkering.
BSD – derived from the original Unix at UC Berkeley – is another family of open-source OSes. Well-known BSD projects include FreeBSD, NetBSD, and OpenBSD. BSD licenses are permissive, meaning modifications can even be re-released as proprietary code (unlike GPL’s requirement to share changes). Despite having a smaller community than Linux, BSD systems power critical infrastructure. For instance, Netflix’s global streaming network uses a customized FreeBSD for its content servers – Netflix engineers report syncing their Open Connect Appliances closely with FreeBSD’s development branch ⁹. Many Internet service providers and academic institutions also run FreeBSD (known for network performance) or OpenBSD (for security appliances). There are also heritage Unix-like systems: Apple’s macOS is Unix-based (its core, Darwin, is open-source) and has been officially UNIX 03 certified since Mac OS X Leopard ¹¹. On the proprietary side, several large companies still maintain traditional Unix systems (AIX on IBM, Solaris on Oracle hardware).
Independent and Community Distributions – beyond major corporate-backed distros, a lively ecosystem of volunteer-driven projects thrives. Debian is a prominent community-managed distro renowned for its stability and strict open-source guidelines. Others like Arch Linux, Slackware, Gentoo, and Solus are fully independent (no single corporate sponsor) and tend to have devoted user bases. These distros emphasize flexibility (rolling releases, source-based builds, minimalism), educational value, or local community culture. Governments and organizations sometimes back their own projects too – for example, India’s government endorsed a Debian-based distribution called BOSS (Bharat Operating System Solutions) to support Indian languages and reduce dependence on foreign software ⁸. BOSS Linux has seen multiple releases (recently 10.0 in 2024) and is used in schools and offices in India ⁸. Similarly, Brazil developed Governo Electronico IF, and Taiwan has Xunilinux, to meet local requirements.
In contrast, many proprietary operating systems remain dominant on desktop PCs – Microsoft Windows and Apple’s macOS control the lion’s share of personal and business laptops. Android (which is Linux-based under the hood) is dominant on smartphones (about 85% of phones worldwide run Android) ⁷. Apple’s iOS (derived from macOS) leads the rest of that market. Proprietary OSes often come with commercial support and tight integration to hardware, but they limit how users can modify or share the software.
From a user perspective, private individuals enjoy great choice: they might pick a user-friendly Linux distro like Ubuntu or Mint for home use, or stick with familiar Windows/Mac if they have specialty software needs. Tech hobbyists and privacy advocates often prefer open-source desktops (GNOME, KDE, Xfce, etc.) where they can change everything. Corporations may choose a mix: many run Linux on servers and in cloud infrastructure (see below) for cost and performance, while still deploying Windows on employee PCs for business apps. The bottom line is that the open-source and proprietary models now both offer robust ecosystems, and users can often mix-and-match: one company’s server farm might be entirely Linux and open-source, but its office computers might be Windows or Mac with some open-source applications on top.
Real-World Examples Around the Globe
Today’s software choices are illustrated by many international examples and case studies. Governments and companies worldwide have undertaken major migrations or developed projects to leverage open-source benefits. For instance, the French National Gendarmerie (military police) began transitioning thousands of PCs to an Ubuntu-based system called GendBuntu. Starting in the mid-2000s, they replaced Microsoft Office with OpenOffice (ODF), switched browsers to Firefox, and by 2008 began an “industrialised” migration of desktops. By 2013 they had over 37,000 PCs running GendBuntu, aiming for about 72,000 by 2014 ⁴. The Gendarmerie reported large cost savings and reduced vendor lock-in as a result.
In Europe, other government initiatives have embraced open standards and software. The UK Government, for example, announced plans to standardize on the Open Document Format (ODF) and to encourage open-source office tools, aiming to reduce its £200+ million Office software spend ³. Many cities and municipalities have experimented too: Munich’s famous LiMux project (launched 2006) migrated over 12,000 of 15,500 city desktops to a Linux environment by 2012 ¹⁰, citing increased autonomy and security. (Munich later reconsidered and planned a partial return to Windows, but still pledged to favor Free Software when possible ¹⁰.) Similarly, the City of Barcelona has been steadily replacing proprietary systems with Linux and LibreOffice to cut costs and support a local free-software economy (a roadmap was released in 2015).
In Asia, countries invest in localized open-source projects. India’s Union government officially endorsed BOSS Linux (the distribution above) to promote free software in administration and education ⁸. China developed Kylin OS (and later Ubuntu Kylin) aiming for a domestically controlled operating system. Open-source is also popular in Japanese industry and research, even if Linux’s desktop share is smaller there.
In South America, Brazil stands out. A 2017 survey by the Brazilian Internet Steering Committee found 93% of federal agencies using open-source technologies, and 85% of them even developing new open-source solutions in-house ⁵. The Brazilian federal government introduced a policy (13 years ago) mandating OSS when possible, and today agencies commonly use Linux servers, Android devices, and open-source software stacks. Mexico’s government likewise requires preference for OSS in procurement, and agencies like INEGI (census bureau) use Linux for server farms.
Major corporations also increasingly rely on open source. Tech giants like Google, Facebook, Amazon, and IBM build their infrastructure almost entirely on Linux. For example, Netflix not only serves much of the Internet’s video traffic, it built its own content delivery network on FreeBSD ⁹. Netflix engineers continuously merge new FreeBSD kernel improvements into their network servers, contributing fixes back upstream. Hardware manufacturers and cloud providers (Amazon Web Services, Google Cloud, Microsoft Azure) all offer Linux-based servers – in fact Linux “dominates” the data center: 96.3% of the top one million web servers run Linux ⁷, and all of the world’s fastest supercomputers (Top500 list) run Linux ⁷. Android (the Linux-based mobile OS) controls about 85% of smartphones ⁷, meaning the vast majority of devices in users’ hands rely on a free/open kernel.
Even historically proprietary companies have embraced open source. Microsoft, once seen as a staunch rival of “Linux”, reversed course in the 2010s. It open-sourced key products (releasing .NET Core, acquiring GitHub, porting Ubuntu to Windows, collaborating on OpenAPI and IoT projects) and in 2016 even became a Platinum member of the Linux Foundation ⁶. As one Foundation press release noted, Microsoft “has grown and matured in its use of and contributions to open source” and works closely with Red Hat, Canonical, and others in cloud and enterprise solutions ⁶. Today Microsoft Azure supports Linux VMs, and even macOS’s Safari browser uses open WebKit (from KDE). Similarly, Apple has released large parts of its macOS Darwin core as open source (though macOS and iOS themselves remain proprietary). Many telecoms, financial firms, and manufacturers deploy Linux and open source in critical roles for the same reasons: cost savings, flexibility, security, and control.
Across the spectrum – from hobbyists running Ubuntu on home PCs to governments moving hundreds of thousands of machines to open-source platforms – the software “panorama” today is richly varied. Free and open-source options coexist with proprietary products, each serving different users. Companies large and small balance open innovation with the need for professional support and unique features. Crucially, the lines are blurrier than ever: many products are hybrids. For example, Android is free software at its core but drives proprietary phones; Mac computers ship Unix-certified kernels under closed interfaces; even Windows 10 ships a Linux subsystem.
Choosing the Right Path: For an individual or organization, deciding among free, open-source, or proprietary software depends on priorities. If user freedom, transparency, and community support are vital, FOSS is compelling. It can also reduce licensing fees (as millions of PCs show with Linux or LibreOffice). If a polished proprietary package or specialized tool is needed, one might accept closed licenses. In practice, most users mix both: running Linux servers and browsers like Firefox (open), while also using a commercial graphics suite or cloud service (closed). Some businesses opt for open-source distributions with paid support (e.g. Red Hat Enterprise Linux, SUSE) to get the best of both worlds. The key is understanding the trade-offs: adopting FOSS usually means more independence and security auditing, while proprietary often means vendor-managed ecosystems.
Conclusion
The software world today is a vast panorama of choices. The free and open-source movement, born in academic and hacker culture decades ago, now shapes the backbone of modern computing – from Google’s data centers to the smartphones in our pockets ⁷. Proprietary software remains powerful and prevalent, especially on the desktop and in entertainment. Each model – free/open and closed – has unique strengths. Rather than fighting, they now often complement each other in hybrid environments. For readers and organizations, the message is clear: be informed and pragmatic. Consider what freedoms you need (to study code, avoid lock-in, or comply with standards), and don’t be afraid to blend approaches. Whether you’re a Linux enthusiast, a BSD sysadmin, or a business evaluating licenses, the diverse “software panorama” means you can pick the tools that best fit your vision and values.
