jrepin points out an article by Richard Stallman following up on the 30th anniversary of the start of his efforts on the GNU Project. RMS explains why he thinks we should continue to push for broader adoption of free software principles. He writes, "Much has changed since the beginning of the free software movement: Most people in advanced countries now own computers — sometimes called “phones” — and use the internet with them. Non-free software still makes the users surrender control over their computing to someone else, but now there is another way to lose it: Service as a Software Substitute, or SaaSS, which means letting someone else’s server do your own computing activities. Both non-free software and SaaSS can spy on the user, shackle the user, and even attack the user. Malware is common in services and proprietary software products because the users don’t have control over them. That’s the fundamental issue: while non-free software and SaaSS are controlled by some other entity (typically a corporation or a state), free software is controlled by its users. Why does this control matter? Because freedom means having control over your own life. ... Schools — and all educational activities — influence the future of society through what they teach. So schools should teach exclusively free software, to transmit democratic values and the habit of helping other people. (Not to mention it helps a future generation of programmers master the craft.) To teach use of a non-free program is to implant dependence on its owner, which contradicts the social mission of the school. Proprietary developers would have us punish students who are good enough at heart to share software or curious enough to want to change it."
