I will never understand how they lost that lawsuit. If a parent gives a child access to their credit card they deserve what happens. I totally agree with your second point, IAP has spoiled gaming on iOS and that's the fault of the game devs for taking advantage of it. However if it didn't work they wouldn't do it and obviously plenty of people spend money via IAP. It's also their only choice. People are willing to spend more small amounts of money over time than paying a fair price up front for the game.
