I don't know enough about it to know why they're not supporting MPEG-DASH on iOS (although, weirdly, desktop Safari does support it), beyond the obvious, "it's not Apple's HLS," answer. If it is just that - Apple don't want to support it because it's not their standard - then I'd be inclined to agree with you. Is there some technical disadvantage to MPEG-DASH vs HLS, or impact on the user, battery life, bandwidth usage, or whatever?
I actually don't consider their intentions to make any difference here. But the damage they are causing is real, and it spans many areas way beyond iOS itself. So IMHO there should be some way to prevent it legally. But again, may be current law doesn't address such situation. Then it should be fixed.
HLS is just one example. I brought it, to demonstrate how such ban on competing browsers can cause bad effects to everyone else, even to those who have nothing to do with Apple and its products.
