For personal and financial reasons, I have not and will not buy any 4e books beyond the core 3 and FR campaign setting (my last RPG purchase). I haven't signed up for DDI, and I haven't been on the WotC website for about 6 months. I don't have a particularly huge hatred for 4e; it was just a combination of circumstances that led me to decide not to invest in a game I never expect to play.
That said, a few months ago I...acquired...a large digital collection of official 4e material. Honestly, I thought it would make a good, helpful, or interesting reference for my current game building exercise, or at least be interesting reading. I didn't really set out looking for it, but it came up and I grabbed it. I thought about getting more.
After WotC's recent actions and statements, I'm not going to. And I'm deleting the files I do have. And I'll likely sell my physical books.
I don't feel guilty, and I don't feel vindictive. But I have realized that 4e just doesn't interest me at all. I'd rather have $$$ and my drive space back. My digital acquisitions have gathered digital dust on my hard drive. I haven't even "cracked open" most of them. I've looked at PH2 on the shelves, and I can't even work up the interest to pirate it.
Pirating something at least hints at interest, and I don't have any. I'd actually love it if pirating of 4e stopped altogether - maybe then, if sales decline as well, WotC will pull back and think about making a game that excited me again. I'm not betting on it, though.
Ah, well. Swords & Wizardry is pretty darned cool.
