Yes, there needs to be a lot more uproar for these cases as well. One of the most appalling cases is that of macOS. To distribute your app (as a .dmg for instance), you need to sign up and pay for a Developer ID, sign the app with a Developer ID certificate and then notarize it, EVEN if you don't intend to use their App Store.
If you want to sign using a cert trusted by apple, and distribute on their infrastructure, you do need a paid account.
This seems like a reasonable compromise, quite honestly. That is based on remembering the bad old days of just having to trust that the software you downloaded from some random shareware site hadn't been modified maliciously.
Users will just assume the app is broken, a virus or that you're a hacker, all because of the way macOS treats apps from developers who didn't pay the Apple tax or submit the app to Apple's panopticon for approval.
Users should not have to know some cursed and arcane ritual to run the apps they want to run.
However, any attempt by Apple to scare vs. just inform/confirm would be a dark pattern we don’t need.
(Might be quicker for some in Terminal if supported.)
I think it used to be Right Click > Open, then confirm.
