Please don't strawman. I wasn't saying they should put a woman there just because of her gender, I was saying they should have a woman there because of her talent, drive, accomplishments, etc. AND her gender. I don't know whether you're trying to tell me that it's *impossible* to find one such person from all those companies...or? My assumption is that it was possible to find at least one, but Sony didn't make the effort to do it for this particular event they're hosting. If Microsoft host a similar event for their xbox, and they can have at least one female team member for the presentation because they're willing to go the extra mile in order to find one, I'd lay the blame squarely at Sony's feet.
I don't blame Sony for the 'industry problem', like I said, everyone just sort of ended up there 'by default'. The point I think you're missing is this is a PR issue. Judging from their intro, Sony did want to attract a wider audience. It's a PR oversight to not go the extra mile at this PR event; if they had, they would've done a better job. But I'm optimistic that they'll learn something from this and be more mindful about their image for future events.
It's pretty fucking impossible.
Also why are you bringing up this criticism now compared to thousands of conferences from all developers where they have no women?
This feels like some TumblrInAction shit.
