alt Hacker NewsWell, 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.

...in which case having a cloud backup of the full disk encryption key is pointless, because you don't have access to the disk any more.
The problem is mass-surveillance and dragnets. Obviously if the state wants to go after you no laws will protect you. As we've seen they can even illegally collect evidence and then do a parallel construction to "launder" the evidence.
But One-drive is essentially a mass-surveillance tool. It's a way to load the contents of every single person's computer into Palentir or similar tools and, say, for instance, "give me a list of everyone who harbors anti-ICE sentiments."
By the way my windows computer nags me incessantly about "setting up backups" with no obvious way to turn off the nags, only a "remind me later" button. I assume at some point the option to not have backups will go away.
