I believe people in HN also remember the days before we had MMUs.

And I'm sure everyone remembers ransomware.

No one is saying OS shouldn't have security measures, permissions/entitlements and app sandboxing, user land, etc.

I still don't understand why my desktop/laptop is allowed to be 'owned' by me. but my iPhone is a closed-gardened where I'm just a guest in a device I own. and that's nearly what Google is now doing.

What review processes on computers?

> They were a massive issue before, and now they're barely a thought for most people.

Even on desktops... where there are no such review processes. Apparently we've found other mechanisms to reduce those issues, without app stores everywhere.
