> Apple's solution is iCloud Keychain which is E2E encrypted, so would not be revealed with a court order. Nope. For this threat model, E2E is a complete joke when both E's are controlled by the third party. Apple could be compelled by the government to insert code in the client to upload your decrypted data to another endpoint they control, and you'd never know.
Yeah and Microsoft could insert code to upload the bitlocker keys. What's your point? Even linux could do that if they were compelled to.
An open source project absolutely cannot do that without your consent if you build your client from the source. That's my point.
