The key difference is that Microsoft prohibited these things on hardware sold by other OEMs. Microsoft tried to control what Dell and HP could install on their computers - and not just those running Windows. Apple controlling what Apple installs on Apple hardware is a completely different ballgame. Honestly I think Google is more likely to run afoul of this with their "anti-fragmentation" clauses. Google requires that OEMs that want to ship Android may not also ship products that run Android forks. That's not too far off from Microsoft's "per-processor" licensing.
