In essence, the current free 2 play model equals a slot machine in a bar. It preys on the poor people who get hooked, tries to hook them as quickly as it can, and in pure business logic, tries to get as much out of them as possible.
Where insult comes to injury is if you look at the App Store revenue numbers. No matter when you look at the top grossing lists, the first 3-10 titles are free 2 play titles. So most of our bars have turned into casinos by now already, trend rising. That is very shortsighted, bad for customers, bad for Apple and bad for the industry.
And for me it just boils down to: I don't want to build slot machines.
