It's beyond absurd and desperately needs to be addressed. Too bad both the government and corporations stand to loose too much that I doubt it will be treated seriously.
How would a successful antitrust verdict against Apple further the NSA's implicit dogma of "insecure by default"? Especially if it winds up breaking up Apple into many pieces. It's far easier for a centralized tech industry to bend the knee to the NSA than a distributed one.
easier but you get less data. There's thousands of small knees to get to bend to. More points of failures for public outings Centralizing it to one company makes everyone's lives easieer.
Furthermore the NSA/FBI/CIA want all their spying behavior to be secret. If you have to bend a lot of small knees then someone's going to fib before they get the data they want. And moving off a small company that's bent the knee is way easier than moving off FAANG, which can keep secrets[0] and has your balls locked in a vise.
[0] Because, among other things, the whole "Surprise and Delight" doctrine demands internal controls and secret-keeping discipline not that far off from an actual intelligence agency
Forcing Apple to hand over data to a third party for commercial reasons (not needing a warrant) is much simpler than whatever scenario you have worked out.
Given recent events, I don't think Amazon Prime is that necessary anymore.
Mail servers, sure. The big issue there is another annoying pseudo-monopoly issue where so many major email servers assume anything not from [major email server] is spam, so you may not even get to communicate properly. More sticks for the fire.
I'm anything but a major mail provider and I don't have any issues. I did have some hiccups around 2008 and had to implement DMARC-DKIM. I use strict delivery so my mail server must delivery all mail directly.
Occasionally people have a vanity domain email that bounces back to me. I have to search the headers for the actual email address and re-send.
Anytime you willing share data with a 3rd party the law assumes you aren't keeping it private.

If you want to keep something private don't share it outside of your house.
