The thing is, piracy actually benefits Adobe.
Without piracy, teens and college students simply wouldn't be using Photoshop. So GIMP would get a higher userbase and more developers, meaning it would get better and more new designers would be used to it. Meanwhile, PSP would sell more licenses, meaning they could invest more in development.
Essentially, PS would lose its dominant position in a matter of years.
