>>103191Richard Mathew Stallman (RMS) quit his job at MIT writing operating systems to dedicate his life to making an operating system that anyone was free to edit, inspect, share, and use for any reason. The operating sytem ended up becoming what most people call Linux, after many other people contributed to it. He was the person who started the "free software movement" a movement to give users control over their computers by promoting software that allows users to edit and share the software freely. The "free" in free software means freedom, not price. His ideas influenced the open source software movement, which emphasizes the practical advantages of free software while while ignoring the ethics related to software.
People (mostly left wing "open source" people) have been trying to cancel him because of his statements regarding sexual assault, necrophilia, and pedophilia. They are also making up lies about him (like that he is anti-lgbt and dosen't respect pronouns), or that he defended Epstein.
This is an example of an article that came out during the first movement to cancel him (it mischaractarizes statements made by him)
https://www.vice.com/en/article/famed-computer-scientist-richard-stallman-described-epstein-victims-as-entirely-willing/https://stallmansupport.org/ is a website defending him.
He is a meme on /g/ due to his large contributions ethical and technical contributions to technology, and due to his uncompromising attitude towards proprietary software. He refuses to own a cell phone, use hotels, use pay toilets, use any proprietary software ever, etcetera.
