Given the sexual harassment and exploitation of women in other industries like Hollywood and how often this is either encouraged, actively ignored or swept under the rug by the executive level of other gaming industry companies I believe that giving this the label of "gamer culture" is just dishonest at this point because it implies that the people playing games are the "true root of the problem". I'm not accusing you of doing that, don't get me wrong.
Enforcing the image of the "evil gamer" is of course an easy way to diffuse responsibility and push it off to some imaginary group (it's not 1995 anymore, gaming is no longer some sub- or monoculture) so that the poor big executives never catch too much negative PR.
I'm sure the people in charge love the "it's a large scale problem of society or gaming culture" narrative.
