I am fine with Apple hosted content being at 30%, but when I have to do all the work for hosting and delivery, 30% is beyond reasonable.

I would even be fine if the rule said that an app developer can provide no link / no in app purchase unless it is through Apple. People using Amazon, B&N, Netflix, last.fm, etc. wouldn't of had a problem because they know to go to the website to buy stuff. The "must also" crap is the problem.
