Well, as long as licensed customers have access to styles, upgrades, or even your products, there will always be piracy. If you don't want your product pirated, don't put it online. I'm not pointing fingers, but there IS and WILL always be someone among us who will release paid products to the pirate community.
If secret government documents have been leaked, what makes you think your $20-$50 style is safe?
Oh and speaking of styles, they can also be ripped, so if you have live demos, chances are your styles are being ripped as we speak(if they are any good, that is).
