Only if you charge for your app - and how much free labor and bandwidth do you give away? Apple gives away millions.
I guess a ~2% fee would cover those costs.
30% of 0 is also 0. They are already cross-subsidizing it.

Nobody said they should be.
If they don't want that burden, which is very understandable, then maybe they shouldn't be the sole God gatekeeper of content? That's a choice, after all, and one they willingly made.
