At the same time, a lot of managers (more than half in my book) are bad at managing people.
There's no way in hell any of us would be ok with our managers treating us the same way Linus treated other engineers. It worked because he's a genius and he controls the Linux project. You had to play by his rules or not at all. Google doesn't have the same advantage - it's not the only game in town.
I think Linus's handling of the Linux kernel is an excellent example of stellar technical leadership in a parallel track. It is what technical companies should look like. Engineers do their thing without worrying about administrative tasks like HR bullshit, salary negotiations, hiring, firing, and fights over who makes the coffee.
