EG in the best of all possible worlds for Microsoft your work, your bank, and Netflix would all refuse to run if you weren't running Microsoft. Realistically Mac is way to big to ignore but it would be awfully convenient if comparative small fries like Linux could be locked out especially if developers could be convinced that running Linux as a locked down service within windows was the only things they need.
On a less suspicious note the TPM enables a convenient way to secure client machines that are owned by your company in such a way as to make it very difficult to access the data therein without manually managing keys.
That would be the worst of all possible worlds. It's literally evil.
Key point, there.
