Define and validate "vast".
Define who is and who is not part of the "community".
These are impossible to validate or verify, its very well-meaning hyperbole.
Brad is making the best possible business decision he can, and he has more access to the actual information required to make these decisions. If anyone could really quantify the popularity (or not) of a given DLC, its him. A lot of the sentiment here, I share, but we should all be careful not to make assumptions. Forum goers are a incredibly TINY percent of the total consumers.
The reviews have spoken, if the "vast majority" love the DLC, unfortunately the "vast majority" are also irrelevant, because they have not written reviews or so overwhelmingly bought additional DLC to convince Brad its worth pursuing over the negative reviews.
Personally, I have no problem with the DLC or the expansion model both have pros and cons... but I don't think rose-colored glasses help either... the expansion model of Crusade and then Intrigue have been far better for the game's reviews to date and apparently that's VERY important to Brad... he's a pretty smart guy, so I'm going bet on him.
Griping about his perfectly logical and reason-based decision strikes me as ... well... nothing good.
