Though that doesn't mean Microsoft couldn't implement a way of storing these keys so that they can't be accessed by Microsoft. Still better than nothing though.
Apple has that figured out. Your keys can be stored in your cloud synced keychain but only you can decrypt that keychain.
That’s why they couldn’t help the FBI to decrypt devices even when compelled.
Microsoft should have done the same. They should never find themselves in a place where they can be compromised like this.
Will this make people care? Probably not, but you never know.
What governments and corporations (and plenty of bad actors in the FOSS world) have done is make this the default; made it easy to mindlessly hand people your privacy without even knowing. Opt-out, if you know the setting exists, and can find it.
