El Mahdi
Muad'Dib of the Anauroch
I have never understood that sort of thing - I'm sorry, but it sounds a lot like, "You produced strawberry ice cream at some time, so I will never buy your chocolate!"
Voting with your wallet is a limited communication tool. If you don't like A, you don't buy A, and if A doesn't sell well, then they know not to do A again. If you don't buy B, they have no way to connect that with how you didn't like A. It fails to communicate your dislike, and so is of no service to either of you.
Plus, if you swear off them entirely, well, then they can write you off as customer - your concerns are no longer theirs. As far as they are concerned, you are no longer part of the market, and your needs, desires, and tastes can now be ignored.
Ultimatums are generally not a great negotiating tactic.
Okay then, what's the alternative?
Near as I can tell, I'm communicating to them two ways: by not buying their products, and by telling them why right here.
Just what kind of reasoning leads a business to decide that what will bring customers back is to rent the books to them (if that's what they're doing). Think editions have caused a split in the fan base...just wait until there's the disparity of 4E players being able to own their books, but older edition players can only rent...
WotC has gotten massive amounts of feedback, they're seeing firsthand that 3.xE is still a viable market (as well as the previous editions), and clamoring for pdf's hasn't ceased in the least - yet here we are over two years on and it's still the WotC Knows Best show.
So what's the alternative? What would you do?
