Apple knows how much they can get away with annoying, that's why they can push updates that slow down your phone, or make devices less repairable.
Privacy is trickier though because it's based on trust not annoyance and it doesn't take much to lose it. I've already lost trust in Apple. What I do trust is that 'privacy' is currently working for Apple to increase their market share. It also conveniently keeps data away from competitors.
