From what I have gathered on Reddit and within these forums, Wizards of the Coast is guilty of a whole litany of crimes, including but not limited to:
- Making new editions instead of just reprinting AD&D over and over again.
- Not being TSR, as if that were a bad thing
- Not asking me, D&D's truest and oldest fan, for my vital input on anything. Not even once. I was standing here the whole time, too. I could have saved them so much time and avoided so many mistakes, but they never even asked me. Why, oh why, didn't they just ask me?
- Inviting the "wrong people" to play MY game.
- Not hiring Larry Elmore, Jeff Easley, and Clyde Caldwell to do the artwork
- Offering delicious pineapple as a pizza topping
- Not using THAC0, not requiring us to roll 3d6 in order, and otherwise updating the rules (see #3, above)
- Having the audacity to publish Magic: the Gathering
- Having the audacity to be popular and -gasp! mainstream.
- Being successful in a challenging industry, unlike my beloved TSR
- Updating D&D for the internet age
- Updating D&D for younger generations
- Not turning back the clock to the 1980s and letting me relive my teenage years
- Making me feel old
- Being cooler than TSR
- Being cooler than me
I'm sure there are more, but these are the biggest ones that I've seen.
