1. It's not a false dilemma, it's more of a question of how to handle the "average Joe" user that doesn't know how to store encryption keys. I don't like how this automatic encryption is implemented, by the way, but sending the keys to MS servers is not the worst idea ever.

2. Bitlocker can totally be used without a MS account and without sending keys anywhere and without TPM... But seeing how most people fail to RTFM we're back to point 1.
