I think if you explained it to the average iPhone customer you might be shocked they side with Apple. The concept of a platform where for free you can take advantage of it and just make 100% of the revenue without cutting in the owner of the platform is completely alien to how things work in what they consider the real world.
I can't just walk into Walmart and set up a stand and make money, if I want to sell in Walmart I have to work with them and give them a similar sized cut. If I even set my stall up on the street I have to pay for permits, certification, suppliers.
Not saying I agree with the App Store tax because I actually don't but I think the way they set it up as a "Store" was very clever in making it seem completely normal when it's completely abnormal compared to all personal computing up to that point, which maybe was an anomaly? Hope not.
