Yes, but none of the toys (or few, and not the big ones) are his. The GPL means the rest of the community could fork Linux from its current state and continue without him.

And he doesn’t really do that much these days anyway. He tries to be hands off as much as possible, because Linux is much bigger than just him, and he won’t be around forever. The biggest thing he personally owns is the Linux trademark. (Not sure how involved he is in the Linux foundation day to day.)
