I sure as hell won't install a browser extension if its source code isn't publicly available; I don't see how the government should or even could protect us from every update made to all of the software packages I import (even if the punishment for malware is severe); and large corporations may be able to get their hands on source code, but I don't trust them either. The FSF may be stuck in the '80s in some ways, but their fundamental principles are solid. I much prefer their vision to one that has users "freed" from source code, trusting large and opaque companies and government agencies, whose interests may not align with mine, to shield me from malicious actors, of which there are many. Honestly, if anyone is stuck in the past and not relevant anymore, it's not the FSF; it's people who downplay malicious actors, fail to recognize that software is often tiny, or updated frequently, or written by someone anonymous or outside of US jurisdiction whose behavior we can't punish with US law. A lot of software is made up of forks too, and not many software forks end up useless like in his anecdote about his company forking Windows... Yeah, this dude obviously hasn't been keeping up to speed since his retirement.
