He's being a bully, pure and simple - using his popularity to shove around others. That should not be tolerated, full stop.
If it was pure abuse. maybe, but history if full of abusive assholes who did amazing things, purely because the abuse isn't by some ignorant asshole, but one who actually knows what they're talking about.
Now, if there's something you don't know about, being abusive is just being abusive. But if you do know your shit inside and out, being abusive can get your point across.
Steve Jobs, Theo De Raadt, and Linus Torvalds are basically the few who are abusive assholes, but everyone also knows that they do know what they're talking about. (In Job's case, the RDF is basically a mirror that says "is that REALLY the best you can do? You can't do it any better if you tried?").
Oh yeah, it's a terrible environment - there are plenty of people who packed up and left Apple after meeting Jobs (many really good people too). Just like there's plenty of kernel devs put off by Linus, and likewise for OpenBSD. Unfortunately, the truth is, they do get results.
And no, MBA types, you can't do it. Only a very limited few can be assholes and get away with it. Chances are, if you're not one of the three people I listed (of which one is deceased), you won't succeed.
