I think we're on the same side in principle. The ability for people to interact with the wider world using general purpose computers that they fully control should be sacrosanct, and attempts to interfere with that such as remote attestation, app store exclusivity, and developer verification are evil.
Sandboxing apps by default is not that. The principle of least privilege is good security. If I vibecode some quick and dirty hobby app and share it with the world, it's better if the robot's mistake can't `rm -rf ~/` or give some creep access to your webcam.
The user should be able to override that in any way they see fit of course.
