Apple’s position is that the average user isn’t supposed to be installing apps from outside the App Store anyway. Who is the average user, you ask? No one who posts to or reads HN, that’s for sure. Your parents, grandparents, and clueless neighbors are all average users. They will benefit from the decrease in malware and increase in assurance that the app won’t do something fishy.

Everyone else will bypass protections and continue as before.
