All I was saying is that creating an app that explicitly works to make piracy as easy as possible and to throw as much pirated content as possible at the user is kind of a dick move. It's doubly a dick move if they end up profiting from it. When money gets involved in piracy I think any grey area that might be there goes away. Now it really is stealing, plain and simple. It's worse than any sketchy lawyered-up studio exec.
How exactly does it stink? Apple provides a service and a platform for selling music, and they take a cut so they can continue to provide said service, which obviously isn't free to run.
And if you're unhappy with the size of the cut they're taking, it's not like you don't have options - Bandcamp (my favorite digital music store simply because they have no region locking bullshit and default lossless with a whole bunch of other format options for one price, the same which unfortunately can't be said of most legal digital outlets) only takes a 10% cut, and if you want, you could always sell directly on your website with the likes of Stripe and such (but even then you're going to be paying some fees). Of course, the last one requires the most work on the artist's part, but that's how it goes - you either pay someone else to do it for you (the cuts on iTunes, Bandcamp, etc) or you do it yourself.
