False analogy. You can’t have your kitchen knife exploited by a hacker team in North Korea, who shotgun attacks half of the public Internet infrastructure and uses the proceeds to fund the national nuclear program, can you? (I somewhat exaggerate, but you get the idea.)

> Systems can be secure and trusted by the user without having to cede control

In an ideal world where users have infinite information and infinite capability to process and internalize it to become an infosec expert, sure. I don’t know about you, but most of us don’t live in that world.

I agree it’s not perfect. Having to use liquid glass and being unable to install custom watch faces is ridiculous. There’s probably an opportunity for a hardened OS which can be trusted by interested parties to not be maliciously altered, and also not force so many constraints onto users like current walled gardens do. But a fully open OS, plus an ordinary user who has no time or willingness to casually become a tptacek on the side, in addition to completely unrelated full-time job that’s getting more competitive due to LLMs and whatnot, seems more like a disaster than utopia.

Some countries do :) Though I think physical analogies are misleading in a lot of ways here.

> Systems can be secure and trusted by the user without having to cede control, and some risks are just not worth eliminating.

Secure, yes, trustworthy to a random developer looking at your device, no. They're entirely separate concepts.

> Most importantly - it's the user who needs to know whether their system has been tampered with, not apps.

Expecting users to know things does a lot of heavy lifting here.
