Protect them from whom? What is the threat model against which Pyarmor
is claimed to protect? Who is the attacker, who is being protected?

So a Python file encrypted this way will be arbitrarily restricted in
how it can be inspected for debugging, performance monitoring, and
testing?

This seems to explicitly treat the user of the Python software as a
hostile attacker. That is not a friendly or respectful position, and I
hope I misunderstand Pyarmor's operation.
