Because generative AI has been built off the backs of everyone, whether they consented or not. Because AI companies (Nvidia, Facebook, pick a company) have pirated enough material to keep any individual in jail for life, and yet they have no consequences and can profit off everything.

If generative AI can not be used for commercial purposes, it also cripples the ability to replace artists, writers, etc., with an AI that stole all their work in the first place and is regurgitating it. Generative AI isn't the issue, and it won't go away (I wish it would, but the world doesn't work that way). It's the way it's being used. Take the profit out of it, and we can all (to some degree) benefit from it. Take the profit out of it, and stop them from hoarding and destroying books/knowledge, destroying the environment, destroying your economy.

I'm sure people more well-read into generative AI can give a better example than a layman who is tired of billionaires and trillionaires doing whatever they like with no consequence, destroying our environment, our jobs, our economy, and now our souls along the way.
