At least the site that offers the game without any mandatory client service still offers it to us even if STEAM/Valve bends knee to the pressure to violate freedom of expression as so many, including itch, have been doing. And they offer a client option that you are free to choose to use or not to use at your own discretion.
I avoided all of the "Interuptions and Interferences" by purchasing it there. I now have well over 400 games in my library there and many of them are uncensored AVNs all while NOT using their client!
