The problem is that GamerGate was created as part of a harassment campaign, explicitly billed as a propaganda tool, and never had a coherent message or structure, neither of which is necessary for a PR operation.

This meant that while the media coverage was generally accurate there are GamerGate supporters who aren't aware of the true origins and now incorrect feel that they were misrepresented — precisely the kind of distraction the original 4chan / burgersandfries cadre were hoping for.
