I was offered to join a group that would promote more games being made with AI by some friends. I don't like the idea, but I don't know how to refuse it

I'm being a little vague with the details for the sake of privacy, but the context is very much true.

Okay so, today, someone people I know, and that are friends of mine, tried to invite me in a group that promote games with AI. The idea would work by "Hire some devs from gaming conventions to make a lot of visual novels with suggestive content, and get a little of cash gains from it because one of them can be successful"

I tried to subtly (because again, they're my friends I don't want to be rude) suggest one of these friends, that people don't really like AI.

His response was that everyone is using AI for everything nowadays, despite people not liking, and that in the end the AI users will outnumber the non-AI users, so the non AI users were just screaming at nothing (NOT MY OWN OPINIONS. This was what I interpreted from his words)

Suffice to say, I don't really like this idea. I find it a bit 'icky'. I don't think it's the right thing to do, and I feel bad for game devs that put their effort to be said to be AI. But I know they're pretty stubborn, and I know them closely. Like, for long years of my life.

My question isn't "what should I do" because I want to find a way to refuse them, it's more "how can I refuse this offer without sounding condecending or rude"
