Piracy is present the mobile landscape too, you could even pirate the old java games. It's higher in Android but also in iOS (maybe even WP7, I dunno). The low price tag keeps people from piracy, I don't know who wants to pirate portable flash games, but a few thousands still do.
Here's the first link I found on a quick search, but I remember reading a few articles about this on TouchArcade.
