Why? Instead of dealing with developers directly, Apple will deal with third-party distributors. They will publish apps the same way they publish media in News+, or music in iTunes. The media will still be available, just not on Apple's terms. Apple sells and streams a lot of music without having a direct relationship with the recording artist. Each aggregator will presumably offer different terms and developers can choose which one they want to do business with. Some may offer a complete suite of services, others may just offer the basics. Far better than the single set of terms offered by Apple.
This will also allow Apple to ink individual deals with the major digital providers directly rather than trying to shoehorn them in with the same terms they offer indie developers. Apple sees value in having Amazon, Netflix, Disney, etc. on their platform, and those companies will likely find value in being on Apple devices. But instead of the 30% commission that they currently offer across the board, they can negotiate their own terms.
Apple can monetize their development tools, that isn't unusual. Developers already pay for IDEs from MS, JetBrains, and others. Apple can also start shipping separate iOS SKUs that match different regional requirements. An EU version might come preinstalled with Spotify instead of Apple Music. Or come with no preinstalled apps at all. It depends on what European regulators decide they want to permit Apple to do.
