Minecraft creator Markus "Notch" Persson says a lot of things. Some of them interesting, others regrettable. As with most humans! This, about piracy, is one of the former.
I've always found it interesting that it's usually independent developers, those whose livelihoods are most closely associated with the success of their games, that are always the most pragmatic when it comes to piracy. And it's the executives at big corporations, many steps removed from development and forced to appease ignorant shareholders, that are the ones championing measures like DRM.
