Some fair points there, AIS ran like absolute dogshit on my machine but the reasons for that game's issues have already been pretty well-covered elsewhere.
I get a solid 40 in HS2 in the most complex maps and H-scenes with every currently available graphical tweak turned on, I get that's problematic for some, but when there's dozens of current-gen "AAA" titles literally locked at 30fps, I'm not so fussed about losing frames in a porn simulator.
I certainly won't be streaming it and having a higher framerate than the next guy isn't giving me any sort of advantage.
I don't know what Illusion are like for patches after release (if at all?), possibly there'll be fixes further down the road either from them, or a REALLY dedicated modder.
Yes, HS2 is a surprisingly heavy load, but so far, every reported performance issue that's actually impacted how the game runs for me (and a lot of people over the last few weeks) has come from mods in the previous repacks, not the game, and those issues have already been patched out.
And as for the "majority" of people not being able to run the game, I see plenty of people across a few forums and Discords I'm in asking whether their dust-filled, ten year-old potato can run this. They probably won't, but that's PC gaming, folks!
You either die a 640x480 potato peasant, or live long enough to become a 4k 60fps snob arguing over which game about dressing-up dollies looks prettier
