Happy to see Apple caught in such a difficult situation. They insist on being the sole arbiter of what software a user is allowed to install on their device, so this is their burden to bear. They could at any point give up their walled garden approach to iOS, but they won't, so they're dragged into this impossible situation of appeasing CCP or appeasing the rest of the world.
FWIW I'm happy they've chosen to allow the app (although at first they didn't), but the whole situation really brings the consequences of controlling a user's device to light. I hope it changes.
I've always accepted their walled-garden philosophy as a security measure, but you know, I'm realizing that it doesn't have to be either-or. They can continue to hold App Store listings to high standards of security and quality, and I'll continue to use it when that's what I want, while allowing people the option of side-loading at their own risk. Most of the problems with malicious apps on Android don't happen because of side-loading, they happen because of Google's terrible moderation of the Play store.
The trouble is that if you provide a mechanism to side-load, people will be convinced to use it without understanding the risks they are taking. See also the recent issues with MDM. In that sense, it kind of is either/or for the average user.
From all the android users who I have some level of intimacy, the only one sideloading an android app is my brother who uses a gps spoofer to teleport his Pokemon Go character around the world without leaving the confort of his chair. He's a dev and poweruser who knows what he's doing.
All the other dozens of users only have apps from Google's app store.
