I think the key difference here is the audience. Offering credit cards to college kids is very different than offering cards to a more mature audience. Especially when you've been teaching that audience how to use credit cards as what they are, tools. There's also a significant difference here in that in your situation, you would have been providing the rewards and you would have had power to artificially manipulate the value of those rewards (make it harder to win your game without reward points. Here, the author doesn't provide the rewards he is simply stating what offers the credit card companies themselves are making. At the end of the day, there is certainly still a moral hazard here but it is also a very different situation than the one you described.
