Not very many businesses, but there are quite a few biiig ones.
Here on HN I often read startup stories about services which, on one hand, “nobody” has heard about, and which, on the other hand, “quickly grew to a couple million users and started having scalability problems”, which then spawns some story about scalability tricks. Always leaves me astonished as to how the heck some another glorified todo list/cat picture thing can rake millions of users so fast, but here we are.
I suspect there are way more niches in which tens of millions of users live, which the rest of us can just be ignorant of. It’s only when you approach a billion users that you can be sure “everyone” at least has heard the name of the service/app.
It's more interesting about the upstart companies who might get big one day.
Edit: Of course, eBay will likely continue to be allowed.
So EU businesses will simply have more options to choose from.
I suppose ultimately, the market is fragmenting and Apple is aiming to pull and set levels to encourage as many developers as possible to stick with the current system.
I suppose they're counting on the fact that inertia and laziness will encourage continued loyalty when it comes to non free apps.
Imagine a new developer publishes a free app without a plan for monetization, and then it goes viral. They would be on the hook for thousands of dollars.
Unless they have a reason to switch most new apps will likely stick to the old model
