I don't know why people bother justifying piracy. You're not talking to your mother.
Is it wrong to pirate something? I don't care. If you make it harder to pay for your product than to pirate it, through DRM or other annoying restrictions, fuck you I'm taking it. If you're gonna be a dick and force me to sit through 15 minutes of ads on a DVD I *PAID $20* for without the ability to skip to the menu (I don't know if they still do this), not only will I pirate it, but doing so will bring me joy.
The bottom line is that people respond to incentives. Piracy will continue to exist regardless of the morality involved. So if you ask people to pay for your product instead of pirate it,then punish them for paying(through DRM, ads, etc), they will pirate it. On the other hand, if you give an incentive for following the law, so many more people would pay. I haven't pirated a song since the second I discovered Spotify, and I would probably pay up to $40 a month for it before I decided that pirating would be preferable. Steam also makes it often preferable to pay. Convenient list of my games. Uninstall with 1 click, reinstall with 1 click. WAY easier than searching for each game, applying cracks, etc etc.
Piracy is now a market force. Companies that accept that have success in preventing it. Companies who scream "but it's wrong!" fail. Right vs wrong? Lol at that question.
