It's unfortunate, but honestly nothing to do with GA. Blame the game publications/websites.
That depends on how you see it. To me it started having something to do with the GA the moment it became clear that what we are getting are winners of the white males games of the year, and not games of the year. In that respect it became the GAs problem today.
They are not the root of the problem, but that does not mean they shouldn't do what they can to secure legitimacy for their show. And as far as that is concerned, blaming the websites is not really going to help.
This being an industry wide problem I totally agree with by the way.
