There's strong stereotypes around people in technical projects, but without technical roles and actively working against the project. But as so often, they're very much true for this individual (the one who posted about the suspension, is part of that stupid "working group" and is boasting about it on "his" socials. I don't think this should be detailed further. Curiously, the same person was also in charge for the last python release, which featured a very political message in its release notes.

"Busybody ideological crusader who wants to foist their political ideology upon everyone and everything around them" would be my take, are you sure you're clueless as to what was meant by it?
