Don't want to move to California? Can't pass the interview? Salary too low in the offer? There could be lots of reasons.
I agree with your other points, but what I'm saying is not exactly that. What I'm saying is that TensorFlow is not a community-led project in the way that other open-source projects are. It's Google-led, and if you don't like it, you can go away or fork it (...and if you fork it, it's unlikely you'll get many users given the Google marketing machine).
(The same complaints have been and are being regularly made against Red Hat, and also Fedora, given that Fedora is basically "experimental" Red Hat.)
