When any server in USA soil can be changed into a backdoor, accompanied with a gag order on disclosure, I certainly do not want all my egress traffic routed into any computer in USA.
And while I may not have direct control over where my data is actually routed, but there absolutely are legal restrictions on where companies may route them.
But from a threat model I would dare to say, if you control the platform (OS, Cloud Service) you can easy bypass encryption or deploy your own keys as well.
In the end it is still a trust question.
I guess it's sort of a good thing that Apple is getting into the business of giving away snake oil to combat people selling it. The big iOS privacy changes that would help are DNS over HTTPS (maybe it already does this and requiring permissions for non-HTTPS network access. Maybe they could limit relay routing to non-HTTPS browser traffic?
Personal data should be protected by TLS (edit: and/or application-level encryption) so packet routing is irrelevant to privacy and data protection.
I am very worried that the demand for protection of personal data (which is good) is mutating into an expectation of fully regional Internets that do not peer with each other (which IMO is bad).
