App stores are no more terrible than the previous software distribution model where you Google the name of the software you want to install, find some site that "mirrors" the download, realize they've repackaged the original app with extra ads and toolbars, keep searching, find the official download link, scroll past all the misleading ads containing download buttons, download the package, and then hope the download runs on your machine.
Anybody complaining about app stores has forgotten how bad the alternatives are. And community-maintained repositories aren't a solution, that's just the app store model but on a smaller scale so it's less of a Target for bad actors. If ubuntu's universe repo had to suffer the same amount of abuse as the play store does, it would crumble in a day.
