A very biased take to be sure. Who is the "they" you are referring to? Who is "the American Ruby community"? Sounds like a thinly-veiled attack on "leftists".
I know plenty of Rubyists in Europe who these days find DHH as a person to be completely odious, not to mention a maintainer in violation of CoC.
IMHO he violated the CoC of the Turbo project. FWIW, I'm by no means a TypeScript guy so I was even sympathetic to his general ideas on that topic. But his handling of it was terrible.
?? Isn't Turbo his own project? Also in the previous comment you mentioned Ruby CoC which has nothing to do with any project that's not the Ruby interpreter/project itself...
