Oh yeah perspective difference so one can feel differently. However, you are giving way too much credit to many apple users who know to “appreciate apple ecosystem and the caveats that come with it”. Many pick apple because other people uses it, because work phone is iPhone, because iOS looks nice, because having an iPhone is cool. Educated and well informed user like many in this forum is a minority, not the norm. When those less informed users encounter issues using their iPhone and couldn’t get it resolved in a timely manner, they will switch to android, without even knowing what sideloading is and how it would transform user experience. Heck, iPhone users getting bored of 15 years of staled Home Screen May just switch to android because their launchers look cooler.
People here want apple to allow proper sideloading mostly know what they are doing or having ample interest to do so. Apple instead put zero trust on end user (CSAM is just another of such example) from iPhone debut till today, insisting “we know the best and every single user is an idiot who knows absolutely nothing. We are their salvation and saviour”. So here we are. No wonder I still can see dumb iPhone users near me, online and such.
