If you presume that we have a technologically omnipotent government that can defeat secure enclaves, secure exclaves, private cloud compute, e2e encryption, etc., then there’s no point in even pretending to play the game you’re trying to. Even open source software has to run on chips that you have to trust haven’t been backdoored by Uncle Sam. Even open source chips have to be trusted to have been manufactured faithfully.
If you presume the government isn’t technologically all-capable, then technical measures can limit and even defeat the observability that even a wildly tyrannical government has into your computing devices. This mindset is both infinitely more useful than yours and more reflective of the world we actually live in. The government now mostly has to rely on 0-day exploits that they hold close to their chest until a target sufficiently warrants burning it.
Your paranoia is beyond hysterical and it presumes that these companies are gleefully giving out our data when it is extremely clear that nothing could be further from the truth. Again, Apple has more than any company proven a track record of tying their own hands when it comes to complying to these kinds of requests. In the absence of perfect options, I’ll happily go with the good ones.
