There are two different questions of fairness when it comes to the App Store rules. Apple always spin it to mean “these rules are applied fairly”, which is certainly not true. Putting aside questions of why Netflix get to do things Hey don’t, it’s pretty obvious that the rules include “don’t make apps in these spaces where Apple has apps” that don’t apply to Apple. It’s also clear that nobody in the App Store team is rules lawyering Apple apps on the rest of the rules, either.
But all of that ignores the larger question, “are these rules fair?”
