Probably a very poor study...
But on the case of our friends that pirated when kids and then bought as adult... you pirated because you wouldn't even be able to play without doing it and then bought when being able. Not that because you pirated when you were children you bought later.
This study is actually pointing devs to do more games as a service model where you can't even pirate it since you have to keep paying forever to play and I dislike the model.
