Linus doesn't write much code anymore. The ones who are responsible and doing the heavy lifting and taking the heat when things break are the often unpaid maintainers. You can't say OP is more apt when he probably never done this work before.

I have to work with a "kernel a-hole". Sure it sucks but when there's some mutex bug in a chip driver, he's the one we can call and fix the problem and push the fix upstream even though he's already overworked. He's an a-hole but I respect his rules because he's the one suffering and pulling in the work and I don't.

Yes the kernel is stagnating (patches and email mailing list, line length limited to be compatible with old tty terminal, etc.) but when you're at the helm of a ship you don't just steer it near the nice looking island just because it looks pretty and there doesn't seem to have rocks.
