They only offer encryption with a known compromised key. How is that useful?
It isn't.. but here in reality they're forced to respond to requests by law enforcement for things such as CSAM -- this is the problem they were trying to solve with the on-device scanning. The plan was this would allow for backups they would not have a key to, and thus be unable to respond to law enforcement.
Here in reality other companies have end to end encryption.
Do they? Consumer level? Or are you able to view your files in the cloud which inherently implies they have that key.
I said end to end. Why would you ask if I meant not end to end?
Because it probably isn't. How do they respond to LEO requests if they're based in the US?
