Successful for whom? If you're talking about the commercial success of apple through lock down behaviour, sure. But there is *nothing* that would prevent them from providing the exact same experience while adding a toggle in settings "allow sideloading". You want the "crisp" experience that comes from apple's strict review process, just use the official app store.
Looking at android till now, it is still possible to offer a "certified" os that is flexible enough for you to use foss stores. The argument pretending that removing sideloading is customer centric are borderline fallacious. I don't think that playing on semantics between hardware and OS changes any of that
