To play (BDFL's) advocate - Linux is an -enornous- project. It's not physically possible for any effort to be unilaterally directed. Linus does not personally maintain the whole thing, it's just not possible. So he has maintainers under him who are in charge of the subsystems - the implication being that he trusts their judgment and technical expertise. There's no other way the system could work, really.

Linus's position, as far as I've heard and ascertained, is that introducing any language into the kernel is going to require case-by-case and subsystem-by-subsystem analyses. He's not going to reject the language wholesale, but at the same time it's impossible for him to wholesale mandate its adoption. "Kicking maintainers in the ass" sounds great but nothing is ever that simple.

I think this is an important point. People believe "dictator" means "complete control" when instead "dictator" mean "authority to make any decision." The difference is exactly what you say, that you still have to rely on the hierarchical structure and trust that your "underlings" are making the right decisions. Complete control doesn't scale very well and even a small project or team has many moving parts and the only way to have full control is to be involved in every part. With scale, rapidly comes the necessity for trust. There's only so much time in a day, and only so much can be done in an hour. Damned physics, always getting in the way.
