I actually know someone who is a full time mom/disney blogger and is quite active on these boards, and has never said a negative word about WDW.
I think the "insinuations" of a PR team here which I have recently been introduced to are in reference to people like you find in all walks of life, in all types of fans. People who will defend Disney to the last, even for some of their more stupid moves.
Just like someone will tell you their Ford is way better than your Telsa or Porche or whatever, because they love Fords, or because they want to defend what they purchased. There is a lot of that here that I have seen, and yes, that includes people who do this re: disney.
Heck the other day on another thread we were told, once again that its only a handful of people here on the Dis that don't like FP+, that the Vast Majority of people love it, that its great and its great for disney. Even when it was pointed out that there is no basis of evidence to make such claims, that didn't seem to matter to the poster.
There are people on these boards who will admit no wrong on the part of disney, who go to great lengths to defend whatever disney does, maybe because they agree, but there are certainly also some who do it because they are fans of disney, and will defend almost everything disney does, period.
