Earlier quoted context omitted.
This is a moot point unless you always verify and check all hardware and software that you use, including communications devices.
You don't need to verify everything yourself. You can verify any small part and rely on the community to verify the rest. Or pay someone to verify. However, for all that you need verifiability , which Apple lacks.
The only difference in this is who you trust. Be it Apple, the community or someone you pay, you're still trusting that someone else's interests align with yours and they did things correctly.
In other words, this is not a technical problem. It's a problem that needs to be solved through regulation, because 99% of the people can't verify by themselves that their devices are actually private and secure.
