Earlier quoted context omitted.
"Laurey LoL statistics indicate players spend an average of $92 a year on the game."
The thing about IAPs in games is that most money comes from whales, people spending thousands of dollars for customizations or pay-to-win items, this rises the average by a lot. It would be nice to see the distribution of payments.
Otherwise as someone noted it's just price discrimination, and in a way that lets people try and play games for free. Really I love what video games have become.
