This is a Big Deal guys. It's not just about the two magazines. It's about the philosophy about how the company regards us consumers overall.
As a source of income to be manipulated. Luckily, companies with negative karma sometimes find it bites them in the bottom line once their customers work out what they're about. Sometimes. I doubt it'll happen in this case, because WOTC has no real competitors.
My stockbroker stopped me from making some bad decisions that would have given them quite a large deal of fees in the short term. Thanks to their loyalty to me, I'm now very loyal to them and they probably have a customer for life.
I also learned the hard way after I fell afoul of it personally that manipulating a customer for the good of your company is a very easy frame of mind to fall into without thinking, but is often transparent to those on the receiving end. I don't intend to make that mistake again.
It's an unusual situation WOTC find themselves in, though; they can eliminate what has become what they consider to be a competitor because that competitor is using their IP through their own good will, and most companies cannot do that. In one way, they have every right to take their bat and ball and go home. If not for their decision to lend out the IP in the first place, Dragon and Dungeon might have done a "no longer exist" five years ago.
In another way, the diagnosis suggested by Monte Cook suggests that they're out to cheat their customers out of a good deal out of self interest, which doesn't speak so well of them, and definitely doesn't engender customer loyalty or good feeling towards them. Negative karma, but I doubt it'll affect them in the long term, most of you guys will probably keep buying as always after this thing boils over.
