I'm going to throw my hat in the ring and disagree with you about this.
I won't get into every single character mentioned, but Quiet from MGSV is completely unjustifiable outside of soft porn. Have you even tried watching the Quiet/Ocelot model swap videos?
However, one area where Quiet is better than the random characters from D:OS2 is that Quiet (and the other examples in the article) is a character who chooses the way she dresses. That's called context. It's a very flimsy context, but it's still a context.
I'll remind everyone that one of my biggest criticisms is regarding the lack of context and/or the weakness of the context. Witcher 3 is an excellent game which includes topless men and women, and I'm a big fan of Game of Thrones -- not despite the full-frontal nudity but perhaps even partly because it's bold enough to be unashamed about sex and nudity. What these two works of art have is a very strong sense of context. You don't see Game of Throne's Brienne of Tarth charging into battle in a string bikini.
