As NerdCubed said in his review, the problem is that all the future generations of gamers are going to experience this as the default. They are going to grow up in a world, in which people actually think this is what gaming is like. That social engineering and scamming people is an acceptable way of doing business.
I remember the glory days of iOS gaming when a man could pay $10 and buy a complete game. Now said game is free and takes $2,000 to unlock everything. Madden 2014 is a perfect example of this. I'd gladly pay $20-$30 for a top notch version of it. Instead, it's free and you get nickled and dimed for play books. This is damaging to the experience of iOS gaming. Sadly, I don't think there is much Apple can do. The cat is out of the bag.
