Developers tend to favor one of these two viewpoints because they either make the culture of play in a particular game something that they can design towards or they make it a fixed property that they have no power over, something they can imagine either completely controlling or being completely helpless to control, and in any event, something easy to summarize in a reductive, mechanical way. They'd rather either than what the culture of play in a particular game really is, an emergent and contingent result of interactions between particular design features, the general cultural history of digital games and their genres, the particular sociological habitus of the players, and the interpretation of visual and textual elements within the game by different players (individually and in groups).
When Aris Bakhtanians said that sexual harassment was "part of the fighting-game community" he was, in a way, perfectly correct in an empirical sense. This is not to say that all or even most players of fighting games, even in competitive gaming, practice harassment of the kind Bakhtanians infamously displayed, but that sexual harassment and harassing attitudes are commonly witnessed or overheard in a great deal of online gaming, as are the harsh and infantile abusive responses flung at people who complain about such behavior or expression. The one truth sometimes spoken in such responses is that outsiders don't really understand how such things get said or what they mean. Outside critics and designers alike would often prefer for "culture" of this kind to be easily traced to the nature of the game itself, either its semantic content or the structure of play, or for the culture of the game to be nothing more than a microcosm of some larger, generalized culture or cognitive orientation, an eyedrop of sexism or racism or masculine misbehavior in an ocean of the same. If that's the case, either there's something quite simple to do (ban, suppress or avoid the offending game or game genre) or the game is only one more evidentiary exhibit in a vastly larger sociopolitical struggle and not an issue in its own right.
Understanding any given game or even a singular instance of a game as "culture" in the same sense that we understand any other bounded instance of practice and meaning-making by a particular group of people, with all the unpredictable, slippery and indeterminate questions that approach entails, means that if you care about the game as an issue, you have to spend time reading and understanding the history and action of play around a particular game. The stakes are very much not just academic (are they ever?): certainly the viability of a particular game as a product in the marketplace hangs in the balance, sometimes an entire genre of game or an entire domain of convergent culture is at financial risk. But also at stake are the real human feelings and subjectivities of the players themselves, both within the game culture and in the ways that those identities and attitudes unpack or express in everyday life as a whole. If we're going to argue that game cultures teach all sorts of interesting and useful social lessons, or lessons about systems and procedures (as we should) then we have to accept that some of the social lessons can be destructive or corrosive. Not in the simple-minded, witless way that the typical public complaint about violent or sexist media insists on arguing, sure, but we still have to ask what the consequences might be.
