I could answer "iOS may be shitty but it doesn't phone home every touch and your health data stays local". I really don't want to argue abour iOs vs Android. I used both. They are both shit made to lock their users in an ecosystem that solely benefits Google or Apple. I really couldnt care more about arguing which is worse, I would just want the market to allow something better than both for me, the user.
It’s not like people really have options to choose when it comes to choosing a smartphone.
It’s easy to have a growing share price when you are a duopoly. You don’t have to serve your users.
