Because some people are just allergic to that lol
I'm not against it.
(Story spoilers...)

I found Aloy's escapade to be kinda cute, but forced.
I didn't even get to know her "girlfriend" well enough for me to care.
Hell I kinda hated that other girl because she always got me in really deep dangerous and unnecessary crap from what I remember.
But specifically that she's gay? I don't care. If anything, I prefer it to her being straight because in my eyes 2 women on my screen are nicer to look at that a woman and a dude.

But some people don't like that kind of stuff, and imo, that's fine. They deserve to know before they get into a game.
