I absolutely dislike the direction that the "vanilla" path has taken, and feel like the objections to it are reasonable given how far into the game we got before it started to get "darker". It is pretty much a blatant bait and switch situation.
That being said, I firmly am against "censoring" content, as you call it. Anyone here calling for a game to be censored are absolutely in the wrong and should be ignored. In the case of the indignation at the aforementioned bait and switch on the "vanilla" route, those are not calls for censorship and you would be disingenuous at best for calling them so.
If a dev gives an option for different paths and then starts to overlap content on those paths, effectively nullifying the players' previous choices, they rightfully deserve all of the vitriol and dissatisfaction that comes their way. This negative response is not calls for censorship, but honesty.
If a player, however, comes in a game that has a path clearly and honestly marked, described, etc. and then complains about the content in that path they are in the wrong and should be ignored. In the case of this game and the "vanilla" path, I don't feel that is what is happening here.
