I don't know whether it is or isn't piracy, but it's hard to take his opinion on this as representative or forward thinking because of how "special" Minecraft is (i.e. it's massively popular). Maybe his goal is to maximize revenue, but it doesn't seem like that. In that case, I'd be more interested in the perspective of someone who's pulling in 30k/year in sales and has the same 70% "lost sales" rate. When you're making millions, there's a threshold above which more money is just more money and doesn't really matter (depending on the person). But the difference between 30k/year and what might be 60-80k/year if there was a lower piracy rate would probably drive me nuts because that's the difference between making a living doing something and not.
