I wouldn't trust apple for multiple reasons:
* because they agree (or at least help) censorship in china it shows that they do not care about the user, they do what is best for them and if that is sharing data with anyone they will do it. It don't understand why apple would help a governments with bad intention in china and not the rest of the world.
* secondly if they really want to protect your privacy why don't they open source some parts of their systems and let people build it (compile) themselves. eg: the T2 chip could be a backdoor, who can prove it's not?
