sudo or equivalent has been around for quite a long time now.

You think regular people can be trusted with sudo? (Absolutely not.)

Yes. It's their computer. We don't need to hand-hold grown adults, that's how we develop computer-illiteracy.

Nobody knows how to do anything because nobody lets them.

This is an interesting question. I started using computers in the late 90s when there were no guardrails and everything was permitted so I know what I am doing- or at the very least only blame myself if I fuck it up.

But your average 20 year old who only knows an iPhone would be out of his/her depth quickly.

Computers are no longer made for me.

To clarify, re-authentication prevents malware from doing what you said it would do. Regular people wouldn't need to use it.

Also all apple telemetry.

----

semi-unrelated tip - on ios, most telemetry options can be disabled under

Settings -> privacy & security -> Analytics & Improvements

However, there is a whole separate telemetry setting:

Settings -> search -> help apple improve search

note that this doesn't show up if you search for it in settings. (try searching for "help apple" or "improve")

and of course the whole "learn from this app" and other siri settings that are all individual settings.
