My guess is Larry could just buy Canonical and turn it into a parking lot. But maybe this is the long game -- Larry is hoping to trap IBM/Red Hat in a suit when they add ZFS to the kernel, but I'm not sure that's how copyright litigation works. If you forgo litigation for years and now decide to sue, I'm not sure you get to assert copyright now.
