Microsoft (and every other corporation) wants your data. They don't want to be a responsible custodian of your data, they want to sell it and use it for advertising and maintaining good relationships with governments around the world.
The same way companies used to make money, before they started bulk harvesting of data and forcing ads into products that we're _already_ _paying_ _for_?
I wish people would have integrity instead of squeezing out every little bit of profit from us they can.
The same can be said of using “allies” to mutually snoop on citizens then turning over data.
Microsoft does not sell / use for advertising data from your Bitlocked laptop.
They do use the following for advertising:
Name / contact data Demographic data Subscription data Interactions
This seems like what a conspiracy theorist would imagine a giant evil corporation does.

FTA (3rd paragraph): don't default upload the keys to MSFT.
>If you design it so you don't have access to the data, what can they do?
You don't have access to your own data? If not, they can compel you to reveal testimony on who/what is the next step to accessing the data, and they chase that.
