I made a free mobile game that's in both the iOS and Play store, and after I realized the $99 fee is not just a one time fee but a recurring fee to keep the app in the store, well of course I let my developer account lapse. I'm not a charity, and it's not worth it for me to pay $100/year just so friends and family can download it. So, for now only Android users can play my game. And same with all of my future free software - it will never intentionally target Apple users, ever, unless Apple changes their ways.
