1) Sure, there's other sites. No where near the amount of people have shown themselves willing to donate through another site so far. Many game makers have talked about how sites like Suscribestar don't bring in near the amount of money Patreon does. Probably for that same reason Steam and Twitch aren't going anywhere. Patreon hasn't done anything that bothers the majority of its users, just us niche weirdos into the unusual stuff.
2) Being a member of F95 does not make you affiliated with the website. Only being a staff member does that. And no, half the games posted here are not made by staff members. Being a piracy site, the majority of the content across this site is from outside creators, some of whom decided talking to the pirates here was at least useful for feedback on their game. Those creators may get a fancy tag labeling them as a game developer, but that doesn't make them F95 staff.
3) Sure, officially she has been 18 in game. Unofficially though, before Patreon starting cracking down on content and lurking in creators personal Discords there was a different story. That's not really important though. Everyone can believe what they want about that.
4) An incest patch is not illegal yet, though who knows what lawmakers are gonna go after next. That said, none of what I claimed can get F95 or Luxee in trouble, because they are not responsible for my claims or actions. Nor are F95 and Luxee responsible for the contents of the incest patch or its distribution. Luxee did not create said patch either. The only people on the hook for the patch are it's creator, the patch's host site, and whatever people that choose to install it.
I don't think you fully understand that stuff you're talking about. I also think you're way more emotionally invested in this subject than is reasonable.
! That being said, I'd love to help with development - i could translate the game to Polish. Hit me up if you're interested
