That was pretty much exactly the scenario at GenCon -- the first GenCon with the 'D&D Experience' was also, IIRC, the last one WotC attended, and WotC provided lots of swag for the VIP tracks. When WotC wasn't at the next GenCon, there was outcry over the lack of swag, though WotC ponied up after-the-fact to try to mollify the complainers.
A lot of people took the complaining as criticism of the way Baldman was running OP, when it was really about the lack of swag.

Perhaps? I don't know anyone personally or met anyone (after Winter Fantasy 2016) at the cons that ran in the eXperience track that was pissed at the lack of swag. Maybe there were a couple who were exceptionally vocal I didn't see. I do know many who were pissed at the lack of quality and quantity of adventures. $150 for 4 forgettable games was just not worth it during Gencon 2016. People were already aware of lack of swag going into it after Gencon 2015's affair. Though to be fair at Gencon 2015, going from tons of free stuff to being stuffed into a cramped room that the lights get turned out on you, is a big shift in direction.
