Rails would have become irrelevant long ago if it wasnt for DHH. Especially in recent years he has been doing an enormous amount of stuff to keep Rails relevant and still the top choice for rapidly building businesses with a small team.

I don't agree with him on political matters but that is irrelevant. He's not my senator, he runs an open source project (and does it really well).

He doesn't run an open source project well when there's a substantial brain drain from the ecosystem due to his loudly-expressed worldview being deplorable.

This is like the fallacy of marketers who only measure slight short-term increases in engagement. It's not success if you get a temporary bump of 5% if you also end up pissing off a ton of people who will never come back. Eventually the whole thing craters.
