Maybe Microsoft needs to deny permission to run Windows on Apple hardware to make them stop?
Right, like they would give a crap.
It's not in their business model, and it simply won't happen. Microsoft's whole business model revolved around putting their OS on any many different types of hardware as possible. Apple is the opposite of that. And only a tiny fraction of Mac users run Windows on their computer. The only loser would be Microsoft, because they would be losing out on selling Windows licenses to Mac users.
