Piracy, for me is certainly not about not wanting to pay. It's about the feeling that the money I pay mostly doesn't go to creators, but to the companies in-between who doesn't deserve it. I don't want to support such an industry.
It also the fact that I want to push for legal alternatives which are as easy-to-use as piracy today. I want to press a link and have a 1080p DRM-free film download in minutes. The cost is not the issue.
I hope that, within 20 years, sharing will be legal. Just because it's written as illegal in the law today, it's not set in stone. Things can change, and for the sake of the creative people, I hope it does.
