Because gamers take the bait.
That's true but I think for many people it's difficult when someone is given a platform to publicly misrepresent a hobby that you care about.
People will think "don't take the bait" after a while but ultimately they will be pushed to "fuck this, I am going to speak up".
The problem is simply made worse when it's people within the hobby who supposedly also care who are giving her the platform and smearing people who dare go against her.
I'd say she is somewhere between a troll and an activist and that's perfectly fine. That's up to her.
People should be able to call her out without consequences though.
You look at what the video game journalism sphere does to other videogame content creators if they are a bit trollish or a bit naughty.
They don't say "don't take the bait" and move on. They grab their pitchforks and go after advertisers or write hitpieces or otherwise try to shut that shit down.
With Anita though it's all good. Batman only has a cape in the Arkham games because straight dudes don't want to look at another dudes ass? Sure, sounds fine, you want us to signal boost your message? You want us to encourage developers to take note?
Anita represents a problem within the gaming industry and community in that people who buy and play games are treated with a kind of disdain.
When she comes along and "calls out" the industry none of these journalists say "come on now this is such bullshit".
Instead it's left to the players themselves to speak up but when they do they are aggressively shut down.
Which in turn leads to these "independent content creators" becoming more prominent because people like them and want to hear their views.
Then that is met with even more fierce resistance from the establishment.
I often think that if Kotaku, Polygon, Eurogamer etc had been the ones to "debunk" Anita's videos early on then probably they would have at least slowed the rise of YouTube videogame commentary significantly. Certainly it would have stopped a lot of things before they even had a chance to get started.
Instead we got "hey guys we're going to give this idiot a platform to bait you all and badmouth your hobby AND we are going to nudge developers towards listening to her advice."
You mustn't "take the bait" though. Just let it happen.
