The thesis is that not putting out enough book releases (splatbooks, as the adventures appear to be repeatedly discounted or ignored) is harmful to the game.
Someone who wanted content that has not been released can agree that that sucks and express that they wish that WotC was producing the splatbooks they wanted, but that does not equal harming the game. Wizards is pursuing a strategy of getting as many people as possible to play and doesn't want bloat to intimidate new players. I suspect that from here on out in Wizards' eyes, splatbook sales don't matter, only core book sales - and if too many of the former hurt the latter, they just won't bother putting out the former.
