Your forgetting the darkest pattern.

Where Microsoft keeps your bit locker keys in your forced Microsoft account instead of letting you save them to USB drive.

Why not at least give the user choice? Maybe I want a simple password to decypt ? Maybe I don't care about encryption.

Then again, it's not my computer anymore. I'm sharing it with Microsoft.

And they don't even warn you that's the case, or prompt you to save said key to a separate location off-device and in your control.
