I happen to be one of those people against pirating Play Anywhere games.
I'm not exactly against piracy. I am against piracy for active developers. If I cannot purchase the game from the publisher or developer, I do not wish to purchase the game at all.
For example: I recently acquired a fat PS2 and planned on buying all of the games I want to play. However, I cannot purchase them from the developers or the publishers anymore. I must purchase them secondhand from a secondhand retailer like Disc Replay. As the developer or publisher isn't seeing a cent of the profit that Disc Replay is getting from me, I refuse to do this. So I setup FreeHDBoot and started pirating games.
Had I been able to purchase discs from the people that made the game or even the people that put it on disc, I would have. But I couldn't. And for reasons I've already explained, I refuse to buy them so some other company can profit. So I steal them. Really, if Disc Replay didn't buy games at $3 each and turn around and sell them for $35-40, I'd have no problem buying games from them. But they're getting 1,000% markup and not even sharing. So any chance I can get to hurt their business model, I usually take it.
But yeah, since these PA games are still being published I am against piracy for them. I can't stop you from doing you, but i won't be partaking in pirating these games.
