A bunch of them show up to complain, mock, cry, and beg for change in pretty much every game that features an untrimmed bush on this entire site. Doesn't matter a whit that 95% of the games here already cater to their cleanly-waxed barbie doll bullshit, there are just a few of them that won't be happy unless every game they are remotely interested in removes every depiction of female hair below the neck. They want every LI in every game to look exactly how they want and it's some sort of personal affront if one looks different, especially if that difference is an abundance of pubic/pit hair.
It'd be one thing if the devs just ignored their incessant whining about hair, but some do cave. It sucks when they bend over because of a vocal minority, but it is what it is.
Best thing you can do is support the devs that do include it, preferably with money but even with vocal support on forums or their own Discords. I have found several that wanted to include it of their own accord and were further encouraged to do so when supported in that aim. But when all they can hear are whining man-children complaining about pubic hair in 1 LI out of a dozen, it starts feeling easiest just to change things.
