Loudly dismissing genuine and legitimate concerns may feel good, but it’s not likely to get you what you want, especially at a societal level.
I agree with you on the risks of this sort of protection! But I understand what it’s like for non-technical folks in a technical society. Their needs do matter.
You’re precisely right, and of course there’s no possible way on Earth that we could create a safe way to allow users to install apps outside of the blessed path. No matter how many steps people have to go through, even if they have to pass a special exam to prove their competence, even if they have to sign something that says they could lose their life savings and submit it to a court to document this fact. There’s just not a single possible way to protect people to an adequate degree.
That the gatekeeper and government benefit from this arrangement is just a happy accident.
