Hmm. Maybe you're right. I didn't read it that way because pirating GOG (or Humble Bundle) games is seriously going out of your way just to pirate stuff. They provide (mostly) unencumbered games, provide a platform popular for indie titles, support multiple platforms (when possible) and are relatively inexpensive. And run frequent discounts. And they give you permission to back up to whatever storage you want.

Some people will pirate no matter what, but I think piracy is mostly a matter of convenience. And it's pretty convenient to just buy GOG games...
