I think he really just speaks his mind, I'm not sure he is trying to be edgy or anything, he always had quite radical ideas and positions. I mean people have been calling him a lunatic for years, he has been fighting for free software and warning people about proprietary software and the obvious risks it carries. Despite being proven right about quite a lot he warned about, people views never really changed about him.
Radical might not be my choice of words, but he's got a certain type of ideological purity around free software that's definitely on the extreme end.
Here's a paraphrased version of what he's saying:
"GitHub [...] has done terrible harm to our community.
GitHub was so bad for free software, all along[.]"
Now, if you were to define "our community" as the open source community, this would be laughable - very few people would argue that open source software has been terribly harmed by GitHub (on the contrary, the rise of GitHub has seen many projects flourish). I don't necessarily think he means the wider open source community, though - he's referring to his own Stallman flavor of free software.
I absolutely agree. His lack of self-awareness and seeming inability to see the generally positive aspects of the growth of open source just doesn't sound radical to me. Quite the opposite in fact.
Sorry I said radical because we use the same word in french but the meaning is probably a bit different, I should have said perhaps extreme or very opinionated?
I wanted to say that he cares very deeply about free software and the whole philosophy of it, which can make him appear as "radical" to some people.
