While I’m a big proponent of open source and creative commons, I’ve understood past efforts to protect intellectual property. Shutting down the power card sites was unfortunate to those of us who found them to be a big aid at the table, but there were many good reasons not to open the door to all sorts of legal challenges later. But shutting down PDF sales with almost no notice and taking them inhouse? It just doesn’t seem to add up. Especially since there’s no alternative in place to buy them.
