Mac App Store Fallout

With the recent Mac App Store announcement,  wide spectrum of bloggers and well known tech sites are expressing concerns.
What especially caught my eye is the comment from Jonathan ‘Wolf’ Rentzsch's (from http://rentzsch.tumblr.com/post/1369652253/mac-app-store) which reflects one of my primary concerns about Apple. He writes:

"Apple, a corporation with billions and billions of dollars in the bank, is taking 30% of small Mac developer’s revenue — an outrageously high fee, more than three times what popular high-end fulfillment provider FastSpring charges. Worse, Apple keeps customer data away from developers, standing in between developers and their users. Customer service and technical support suffer — Apple won’t even allow refunds to dissatisfied customers."

There is no doubt in my mind that Corporations exist solely for making profits. However what I dislike about the way Apple does is that it rips them off folks so badly all the while drawing strict boundaries on what one can or can't do (See iPhone: 4% of market, 50% of profit)
