I think that for better or worse Valve is genuinely committed to lassies faire moderation, they have historically been very hesitant to remove really heinous games. I don't think they're using this as cover.
That changed with Hatred in 2015. There have been a number of them since. It seems that anything that gives Valve bad press is on its shit list, even if the premise theme has been done before by a bigger or more well-known company stateside. If the upcoming Grand Theft Auto game has full frontal nudity and realistically depicted sex scenes, I doubt Valve would give it a second look.
