Well, with respect, I don't think it has anything to do with piracy. It has to to with taking a known business model that has made the company more money then RPGS ever have, and trying to use it to make an RPG more profitable, and bring in a more continuous, longer lasting revenue stream
Seeing how amazingly successful CCGs have been, I honestly cannot fault WotC for the attempt. It is not a moral lapse or anything - it is just a game design we here don't prefer in RPGs.
But then, maybe we aren't the target market. Perhaps they don't expect hard-core RPG players to pick up the cards, and instead are hoping those who play the card games might use this as an excuse to play RPGs...
