"Will no one think of the chillllllllldren?"
Can you please point out all the children actively working on the kernel, and getting treated like the chattel they obviously are by Linus? No? Then what the fuck are you babbling about?
"Why should anyone have to put up with such behaviour?"
Nobody has to. It's not obligatory. No arm twisting or other coercion is involved. Get this: they actually choose to participate, of their own free will. And they can come and go as they see fit. If you don't like it, that's OK, nobody asked you to join in on the fun anyway.
Hope this helps, have a nice day.
(Does the word "perspective" even exist anymore? That's rhetorical.)
