Assume you are 100% right, do you think the games she showed are an indication of the medium growing, in terms of story telling? Assume she is completely wrong about the reasons people use the examples that she points out, and assume she is wrong about the consequences of what is happening. Given all of that, she still is point out pretty terrible narrative in games, that for some reason get more of a pass(in narrative terms). Gamer's expectation of narrative is relatively low, at worst she is making developers use less plot porn and think about what they are actually writing.
I mean, the reason she is so popular is because 1, the hate she gets and 2, there was clearly a market for dissection of narrative in games(using violence) and she filled it. If you want someone else leading the charge(being the brightest figure head), then you will have to find someone who fits the role better and is popular. And since there is very few people doing it.
MrBtongue is the only one, who I found, covered similar subject matters(in an intelligent way), and he only did it once and he posts video's 1 time every 6(4) months. So if you want someone to blame for her arguments being popularized, its the media's fault for not stepping up prior to this, and everyone being fine with it, up till now.
