Because when buy something u have the motivation to play it because it wasnt free like u earned the right to play that game when u pirate it u know u didnt pay for it so don't have that drive or motivation to play because u know u got it for free and didnt earn it.
I was asked to leave a casino in Vegas years ago, because somebody asked me for change for $20 and I made change for them. The casino claimed it was against they're rules and I had to leave. I feel Karma got them back cause the casino was torn down couple years ago.
