It is some mix of priorities along the frontier, with Apple being on the significantly controlling end such that I wouldn't want to bother. Your trust should also be based on prediction, and giving a major company even more control over what your systems are allowed to do has been historically bad and only gets worse. Even if Apple is properly ethical now (I'm skeptical, I think they've found a decently sized niche and that most of their users wouldn't drop them even if they moved to significantly higher levels of telemetry, due to being a status good in part), there's little reason to give them that power in perpetuity. Removing that control when it is absued hasn't gone well in the past.
