This is a genuine question, not an attempt to paint Apple as the be-all and end-all or a paragon of perfection (for all that I'm an unapologetic Apple fan, I recognize that they have serious faults).
I think there is a strong case to be made that the limitations Apple has placed on the iPhone are instrumental in guaranteeing the privacy and (relative) freedom from crap that makes it as good as it is. There is also a strong case to be made that it should be possible to create a phone (or computer) with nontrivial privacy safeguards, but without the specific limitations Apple imposes.
I lean somewhat toward the former camp, as I believe that in a space like smartphone apps, bad actors are both willing and able to do whatever is necessary to make their unethical money, whether that's with extra ads, crapware apps, or just actual malware, scams, and theft. But I would genuinely love to be proven wrong, and I hope that there comes a day when we have a meaningful competition in the space without sacrificing our collective ability to use our phones without fear.
