First, the TFA is about Apple, not the US. The US gov. also attempted to get backdoors from Apple (only to give up and go for the standard security vulnerabilities instead of getting a clean entry point)
Then cloud data stored on Apple servers is still open game, and Apple syncs message on iCloud by default. There's very little incitive for the US gov to burn political will on this issue when it won't matter for 99% of people using the devices. Except the UK gov doesn't get that privilege as the data is on US servers, not UK ones.
