I'll go ahead and say that the WotC folks didn't necessarily do the best job at marketing, but it wasn't abysmal. Still, that's kind of what you should expect when you put math/gaming/writing/fantasy geeks to the dual tasks of both writing a game (something they're good at) and marketing it (something, as a rule, they're not good at).
With that said, I'm entirely fed up with people who still gripe about it. IMO, we're well past the point where the 4e pre-release hype and marketing have any bearing on the current game's reality. I'm amazed that some people have the energy to hold onto grudges so long, just as I was amazed at some peoples' capacity to get offended by self-deprecating cartoons involving gnomes in the first place. And at this point, I think it's largely a personal issue, rather than a legitimate complaint.
I play D&D, and I'll play D&D of any edition. Right now, I run both 4e and 1e. I run a D&D offshoot in Call of Cthulhu d20. I'll get annoyed if someone tries to tell me I'm not playing D&D, or that my choice in games - whatever they may be - is revealing of a deep personality flaw, or a lack of intellect/experience/talent.
But I'm not apologizing for the marketing anymore, because at this point, it's a personal problem.
