I don't get this take. Your bank, employer, ISP, pretty much any tech company, etc. would also share your data with law enforcement if court ordered.
No, what is constantly being brought out as a huge negative when talking about Google and Facebook is them using your data and data about you to make money.
it’s probably nothing to do with USA law enforcement. my reasonable guess is they don’t care much and would go full private. i think the reason here is china. that way they don’t have to have a separate china policy which would draw undue attention to that point.
iMessage can be MITM’d by Apple when requested by the government and you, the user, will have no way of verifying your correspondent’s public key (unlike whatsapp, signal, keybase etc).
