There also weren't any comments about people not being mature or intelligent enough to get their show or that SGA was much cooler than SG-1. No, as bad as their pre-SGU comments were, they never reached the recent level of fail.
IMO, TPTW created this situation by not treating SGU as a full part of the Stargate franchise in the beginning and that carried over to some of the actor's comments when they were promoting the show. Sure, TPTW wanted to take advantage of the Stargate name in terms of using the franchise's "built-in fanbase", but they also seemed to be ashamed of classic Stargate and tried to make sure that SGU was seen as Stargate in name only. They found out the hard way that they couldn't have it both ways.
