That's not how I read their ToS, they are forcing content providers to offer the same price as elsewhere.
They ban pop-up's or redirects outside.
Both of these are good for end users, and user experience. The 30% cut is only going to affect the providers, not the end users, (at least not directly). They are in turn offering a large user base to these providers, in essence acting like a distributor.
If this somehow leads to providers leaving, I'm sure that Apple will back off some of these rules.
