Oh, so Sophia expects the people she's asked to know the personal positions of every writer at these "major gaming publications" (as she says), and when they've Tweeted something in regards to them, then throw them into the spotlight just to prove a point ...Yeah, that sounds realistic...
Those major gaming publications aren't huge. They don't have thousands of people working there. I agree that it is unrealistic to expect them to know many/all of them personally, but you don't need to know someone personally to know that
there are some. If putting someone into the spotlight is inadequate, then pointing to one of the bigger publications and stating that there are a couple working there would suffice, no? Research of the people working there would be up to Sophia Narwitz, then.
I do believe that the lack of right leaning people at those publications is not evidence for some kind of conspiracy (after all, why wouldn't companies be allowed to only hire people they seem fit?), but judging by how many of the extreme left treat others that don't subscribe to their beliefs, I find it personally believable that a 'conspiracy' of sorts exists, in this case meaning that influence is being exerted beyond their own companies by means of peer pressure.
If you take a look at how Colin Moriarty was treated for a simple joke, how the extremist left thinks it's great to cancel people and deplatform them over small things and how Colin actually got his panel cancelled without a reason given at some larger event, it's not unimaginable that certain people in the gaming media try their best to deplatform those they deem unfit.
