I mean Epic, Spotify, and Tinder are wrong here. Apple built the hardware, and the distribution mechanism for software on that hardware platform. Apple has been a closed ecosystem from day 1. It shouldn't have come as a surprise to anyone and they all knew when they decided to create apps for iOS that they were party to a closed system where Apple are the gatekeepers. Don't like their rules? Then, don't do business on their App Store. Simple as that really.
