alt Hacker NewsFor a long time, if you used full disk encryption, the encryption key never left your machine. If you forgot your password, the data was gone - tough luck, should have made a backup. That's still how it works on Linux.
Pretty surprising they'd back up the disk encryption secrets to the cloud at all, IMHO, let alone that they'd back it up in plaintext.

Well, for a consumer notebook or mobile device, the threat model typically envisions a thief grabbing it from a coffeehouse or hotel room. So your key needs to be safeguarded from the opportunist who possesses your hardware illegally.
Linux can be fairly well-secured against state-level threat actors, but honestly, if your adversary is your own nation-state, then no amount of security is going to protect you!
For Microsoft and the other consumer-OS vendors, it is typically a bad user-experience for any user, particularly a paying subscriber, to lose access to their account and their cloud apps. There are many ways to try and cajole the naïve user into storing their recovery key somewhere safe, but the best way is to just do it for them.
A recovery key stored in the user's own cloud account is going to be secure from the typical threats that consumers will face. I, for one, am thankful that there is peace of mind both from the on-device encryption, as well as the straightforward disaster recovery methods.
That's why full disk encryption was always a no-go for approximately all computer users, and recommending it to someone not highly versed in technology was borderline malicious.
"Tough luck, should have made a backup" is higher responsibility than securing anything in meatspace, including your passport or government ID. In the real world, there is always a recovery path. Security aficionados pushing non-recoverable traps on people are plain disconnected from reality.
Microsoft has the right approach here with Bitlocker defaults. It's not merely about UX - it's about not setting up traps and footguns that could easily cause harm to people.
