So technology is irrelevant when it comes to the entire architecture of how public/private key encryption works?

No. How the technology works is irrelevant when the end result is that the government wants the data.

If your boss asks you to build a machine that produces a widget, does he really care what your code looks like? Probably not. In the same vein, Apple can figure out whatever solution they want, whether it involves conventional use of encryption keys or not, to provide a system where the Chinese government can get access to their users' data.

It's really not that hard.

Do you have any proof? Any citations from security experts?

It doesn't take Bruce Schneier to understand how laws work.

And you still haven’t provided proof that it is required or that Apple has uploaded users private keys or given up private keys.

At this point, you're either a shill or a troll or did not earn your high school GED.
