Not sure if the quote in the article was uploaded after your comment, Christoph, but that pretty much covers what you were talking about.

Personally, I find it an interesting situation. Obviously you have people arguing fiercely both for and against the removal, and both have valid points. I think ultimately it comes down to Apple can do what it wants because it owns the store it was being sold in, but whether or not they were right to do so is what I find interesting.

So far I've only been able to find Newsy's coverage of the arguments (at http://www.newsy.com/videos/iporn), but there's plenty of other food for thought out there as well.
