I think it's good! However, fully defined protagonists offer a different experience where an exclusively female protagonist might be able to explore a female perspective or simply give female protagonists a better foothold in mainstream gaming culture (because as it stands the vast majority of extremely popular titles have a male protagonist and there are few prominent female protagonists to talk about, especially those with developed stories and personalities).
I personally somewhat disagree with the way that was expressed in the article though, which is something along the lines of "multiple protagonists will let men who are more comfortable with a male character play as a guy which lessens that game's value as representation". Like, obviously relating a touch more to people of the same gender is not an isolated phenomenon by any stretch, that's part of why more/better female representation would be a wonderful thing, no need to deride male players for preferring male characters IMO. I say this as a guy who usually prefers the design of female characters, finds them more novel, and so plays as them, but I might just be tone policing so whatever.
I also don't think that female representation shouldn't only be measured by exclusively female protagonists, but it's not my place to criticize Sarkeesian et al. for how they frame their research. (And I think it clearly would've occurred to them too, so I trust there's a reason the analysis has been framed this way.)
I don't have a horse in that race but god that male character on the horrible box art looks mediocre at best
