If the encryption is correctly configured then that doesn’t matter. The only vulnerability that matters is in the encryption algorithm and that’s very difficult to brute force or get a vulnerability for. Though at some point you’re dealing with rubber hose cryptography where you have do deal with not knowing the password yourself.
No that only works in some instances. A correctly configured not iOS computer should be resistant to that.
Until they find a CVE they can use sure
Plenty of those in motherboards, TPMs, CPUs, software, OS, etc.
