The problem is that what you describe is the short term positive impact to Tinder. But that’s far outweighed by the long term negative of having your whole business dependent on the whims of Apple. For example, anytime Tinder wants to make an app update, Apple has to approve it. Well, if Tinder goes after Apple with regulators by filing complaints and pointing to antitrust violations, Apple now has the power to mess with Tinders business. Or if Tinder wanted to offer its users a 20% discount as an inducement to subscribe directly with Tinder rather than through Apple, Apple can and does prevent them from doing that right now by refusing to allow Tinder (or any developer) to reference in the app the fact that lower prices can be achieved by subscribing via web. The examples are countless, but essentially the more reliant Tinder is on Apple, the worse for Tinder and the better for Apple.
