I think that your example of the App Store and the Microsoft Store is helpful! I work on both systems at my job fixing computers for consumers. The only thing I dislike about the App Store is that it doesn’t let you install things without first signing in with an Apple ID (the spam levels of pop-up messages trying so freaking hard to make you sign in is infuriating). But the MS Store feels like all the worst parts of the Play Store and really fucks things up if it breaks. I will likely remember your reply the next time I think about Flatpaks and Snaps though. lol
