First issue right there is the automatic assumption the intention here was to promote the game.
This is the troll chatter / hate factory deciding the narrative on their own because they just want to ride the hate train because it feels good to think you are better than someone else because you made the “better” choice.
This is a thing that happens everywhere and when it applies to something you chose to do as a career (such as working in technology) it can be a horrible feeling to get told that your total worth is nothing because the choices you have made invalidate everything you do.
A wonderful person wrote a blog on it that while it IS about contempt in technology, it is still highly relevant to gaming culture where the same thing is happening and it is just plain sad and wrong.
Going back to the tweets, the thing to understand is that for people to make porn (or any kind of unusual content) for something, there actually has to be a liking for the thing in the first place. So while the subject material might be distasteful to many of us and not representative of the community as a whole, there are legitimately people out there that like the game enough to want to do this kind of thing and now their corner of the internet has been viciously attacked by all the haters that were brought in because of those tweets.
They were pissed about this happening, it was like someone coming into your house, destroying all your furniture and “drawing” on the walls.
This is what the Battleborn community ACTUALLY think about all the nasty comments currently flooding the Internet (courtesy of @Solus_Scientist).
TLDR; We don’t care. We are having fun and we don’t care.
