In an ideal world, fiction would be regarded as fiction, no one would declare it trying to subvert society or champion a new revolution, and people would be able to enjoy the stories and characters within a piece of work, and maybe take from it some life lessons without a big fuss over whether it is, or isn't, meeting some externally placed social checklist first.
We don't live in an ideal world, and so the content of this interactive story is torn apart by 2 camps. The first camp, doesn't want ideas or notions being inside a work that challenges the status quo or makes people question how things have always been. The second camp, doesn't want ideas or notions being inside a work that doesn't challenge the status quo or makes people not ask questions on how things have always been. Both sides are incredibly intolerant of any opinion that isn't goosestepped in line with their own, and have no problem letting the whole world know how awful a story is for not catering to their political ideology.
This is why threads like this, and ideas like this, crop up on both sides. Whether a story is too conservative or too liberal, too oppressively pro-system or too social justice heavy. Because 5% of the viewers don't like change, and 5% of the viewers want everything changed, and the 90% of other viewers are left in the middle, hoping whatever gets made has a good story, good characters, and a decent enough presentation.
Nobody but those heavily invested in ideological grandstanding seem to care whether a character is male or female, straight or gay or bi or any combination that make up the lgbt community. People don't care what ethnicity the character is either, because most time it doesn't really matter in face of the story. People care about having characters they like and can relate to, stories that engage in intrigue them, and a plot that can hold their interest throughout the telling. A game becomes too social justicy if it puts certain elements such as a characters gender or race before the other elements above, or when those talking about the game focus too heavily on those aspects and not the story, plot, or characters.
I like to use the show Legend of Korra as an example of this because it highlights where peoples values actually are, and its a perfect example, being the sequel to the show and having the odd quark of reversing the gender roles of the main 4 characters of team avatar, with the previous formula of 2 girl benders, 1 non-bender guy, and a male avatar, becoming 2 bender guys, 1 non-bender girl, and a female avatar. People criticized the first 2 seasons of Korra due to a lack of likeable characters, a somewhat weak plot, and a odd way of presenting a story, but very few if anyone criticized korra for being a girl. In fact, as the series went on, the character who seemed to draw the most fan criticism wasn't korra or any of the female characters, but the 2 male leads Bolin and Mako, the former for being semi-stuck as comedic relief and the other for not being written as well as they could. As season 3 and 4 came and went, people praised it because it managed to tighten its story, get better at writing its characters as well as introducing new ones, and for having a nice pacing to its plots.
Overall, it shows that most people really only care about having characters they can enjoy, a story that can entertain them, and a plot pacing and presentation that can keep them hooked and engaged.
Does bioware do this? Yes. Yes they do. They allow you room for your personal politics but never let it detract from characters or the story, and they don't derail the plot with it either.
I think the bigger question here shouldn't be if having SJW themes increases sales, but rather why so many reviewers are starting to inject their personal political views and biases into the medium where most people don't care about that stuff.
