I think, avoid race and gender because we've already been in that minefield recently, that the dead Redgars are a statement about marketing interfering with the creative vision.
I find it comparable to Battlestar Galactica, when marketing asked them to have "a birthday party or something" and they did the 1000th landing ceremony where like 7 people were killed. I think the dead Redgars are a message to marketing that says "If you force us to change our vision, we don't have a choice, but you're not going to like the end result."
If it were simply a case of this, the dead Regdar thing wouldn't have gone on so long, even extending into the 4E book -- where there are no pre-built characters! (far as I know, only read the opening chapters, races, classes, skills, feats, items, equipment, and combat chapters)
No, to me, there's clearly more malice going on than just getting back at the marketing people. Unless the thing in the Rituals chapter was just more re-used artwork.
