Brad Wright has been frequently been associated with the comment that "Conservatives killed Stargate." In fact, I think this is a misquote. I can't find anywhere that he specifically said this, but I have found plenty of comments with resentment that people didn't come over to the new show, and some of 'em are of the sort that could be interpreted to mean that, whether he did or not.
SO whether he meant it or not (I personally don't think he did) it's become a matter of fannon that we pulled the plug on MY favorite franchise.
So did we? Maybe.
