If you really care about corruption in games journalism (and I do) then it makes no sense to continue rallying behind this banner that was tainted from the start.
No it was not. Again, where are people getting this bizarre idea? It was created by Adam Baldwin, on twitter, specifically about games journalism and the game websites silencing discussion of games journalism. It seems really hard to believe that these constant claims that #gamergate was started to attack someone (who?) is all honest ignorance rather than deliberate dishonesty.
