... communication and wording are far from professional in the kernel team. Most core-devs would be dismissed on their style of interaction alone if applying to any serious professional elite position. Imagine applying for an astronauts programm with Linus style of talk for instance. He wouldn't stand a chance.
Of course, professionally, Linus is right just about 100% of the time and also can rightfully be super annoyed if some dimwit wastes his and everybody elses time, but the discourse in the kernel team is notably imature at a measurable pace. That includes Linus. Such, that it actually makes it into the news.
He'res an example, the first line a Linux quote from memory:
"You're so dumb you couldn't find your mothers tit as a baby"
"This is a very very stupid idea and A,B and C are blatant beginners mistakes and no one on the mainline will even attempt to merge it. I suggest you look into your stuff more thouroughly before sending out pull requests and perhaps redo your review process. This is the second time and if this happens again I'll ask X to take your branch out of branch YZ. Your wasting my and everyone elses time. Stop that. - EOM"
See? The second line is about the most shaming rundown you can get as a professional or elite kernel dev. It's actually more harsh then the first.
I can totally see why she left the kernel team.
