That's not really true in practice by all public evidence

> the automated CSAM reporting apple does

Apple does not have a CSAM reporting feature that scans photo libraries, it never rolled out. They only have a feature that can blur sexual content in Messages and warn the reader before viewing.

We can argue all day about this, but yeah - I guess it's true that your phone is closed source so literally everything you do is "under the complete and sole control of Apple."

That just sends you back to the first point and we can never win an argument if we disagree about the level the government might compel a company to produce data.
