I think Lee hit exactly upon what the article is about:
That was exactly what I thought: $1000???
And yes, that's what the article seems to be about: Disneyholics and how their "addiction" is exploited by the company. I think it isn't a coincidence that the two people being portrayed as big Disney fans are both people who have a history of a former addiction: Peter Werner with alcohol and drugs - and he is even honest about how he just replaced the drugs with the Mouse - and Doug Moore with gambling.
And the question about whether D23 is really worth it and that it may not be what the fans want isn't something which only Pete Werner might have said on his podcast. Look at the "Are you 23?" thread here on wdwmagic (I even dug up the link for you, the discussion about D23 starts
here). Just as I remembered there were quite a few people saying that this was not what the fans wanted: a chance to buy a limited edition pen for $849 for example. However, in hindsight, that might have been a phenomenal deal compared to those $1000 sorcerer passes...
All in all it seems like the thing Disney is trying to do is to shape the definition of Disney fan in the way they would like the fans to be: If you aren't 23, you are not a real fan. The same goes for their effort to marginalise independent Disney fan sites with their own social media efforts.
