Rather than demonstrating that the designers were criticising anyone's gaming style, I think that providing that particular quote as an example more accurately demonstrates how easy it is to take a quote out of context and then get upset about it for reasons that don't really stand up to closer scrutiny.
Bingo. Taking a quote out of context is probably the best way to have someone misconstrue someone's else's meaning and generate an emotional response. Its done by politicians to demonize their opponents, by news agencies to generate needless sensationalism, and in this case by people angry with WotC to make their point they were demeaned or mocked. The full quote (and indeed all the quotes cites so far), when also shown with their proper context are not demeaning at all.
Another example, from the videos on the previous page:
"We made character advancement fun..."
The actual, in-context and non-edited quote?
"We have made character advancement a fun and meaningful thing at every level of play. We have made high level play as playable and fun as low-level play (much applause). We have made the player and DM experience easier by streamling rules mechanics in places where they needed it, by improving overall presentation and layout of our books, and with the online tools we'll be talking about a little bit later. We have simplified stat blocks...A LOT (much applause)."
I don't see anything objectionable there. He wasn't saying 3.x was unfun, but addressing issues people had with 3.x even before the announcement of 4e. If I'm not mistaken, these were some of the major issues a huge number of players had with 3.x. Specifically, the "fun" comment was made due to a number of people saying there were "dead" levels in 3.x when a character gained nothing but skill points, and maybe a BAB or save bonus increase. Isn't it more fulfilling to have your character progress and have new options every level, rather than these dead levels? 4e has addressed these problems, and Pathfinder has even tried to address several of these issues.
Basically, a lot of this comes down to people wanting to find a reason to be angry, and using whatever is at their disposal (in many cases out-of-context quotes) to justify their arguements. And this is understandable- as humans we tend to remember outlier events that get our attention, and hearing or seeing something which produces an emotional response resonates with people- thats why politicians and news agencies do this. But this sort of thing also doesn't reflect reality, or the true meaning of statements by those that said them.
If you don't like the game because it doesn't appeal to your personal preferences, thats cool- I can respect that. If you have to resort to fabrication and emotional manipulation, and then present that information as fact, then its a whole different matter.
