Free Open Source Software Month - Free Open Source Software Month is celebrated to recognize the cooperative approach to computer programming, open licensing, and distribution of software.

Free Open Source Software Month 2025 – February 2025

Free Open Source Software or FOSS is celebrated every year in February to appreciate software that is both free and open-source where any user has a license to use the software and the source code is shared so that people are encouraged to voluntarily improve its design. It maintains the software user’s civil liberty rights, protects their privacy, and gives users more control over their own hardware. Although there are strong similarities between free-software licenses and open-source-software licenses, advocates of each often have disagreements with one another. FOSS was created on neutral ground.

History of Free Open Source Software Month

From the middle of the 20th century to the 1980s, it was common for computer users to have the source code for all programs they used, and the permission to change it for their own use. Source code was commonly shared by computer users, often as public domain software.In 1983, Richard Stallman announced the G.N.U. project, aimed at setting a precedent in open-source software. The G.N.U. operating system launched in 1984 and was followed by the establishment of the Free Software Foundation (F.S.F.).Eric Raymond published “The Cathedral and the Bazaar” in 1997, which examined the hacker community and principles of free software. The paper received significant attention in early 1998 and heavily influenced Netscape Communications to release their product as free software, better known in modern times as Mozilla, Firefox, and Thunderbird. This development led to Raymond leading a team of people to adapt the F.S.F’s free software to the commercial software industry. The free software movement was therefore eventually rebranded as ‘open source.’Despite the apparent goodwill behind the commercialization of open source, software vendors became insecure with the whole idea of it. However, the success of FOSS operating systems such as Linux, B.S.D., and the companies based on FOSS such as Red Hat, have changed the software industry’s attitude and there has been a major paradigm shift in commercial thinking regarding the development of FOSS.

Free Open Source Software Month FAQs

What is open-source software?

Open-source software is software that isn’t limited by private licensing but is rather free for all users and has publicly available source code.

Can open-source software be commercialized?

Yes. The ideal way to monetize open source is by building a commercial software extension to one’s free offering.

What is the difference between FOSS and free software?

Technically, both mean the same thing as they operate along the same lines providing software that is easily accessible and which respects user freedoms. The difference is in the philosophies of the members of each.

Free Open Source Software Month Activities
