Currently only Content Creators can choose to disable AI Generative Training for their channel, a process which is not simply or straightforward because, as stated by Twitch and Amazon's fallman, Mike Minton, no one would opt-in if it werent an opt-out.
As a viewer however, I do NOT want Twitch to use my comments as AI training for Amazon to sell or collect. I have no desire to part of this process, program or industry. As a paying custom to Twitch, I respectfully refuse Twitch and Amazon's right to my comments, and demand the ability to disable any AI collection of my content or commentary. This is not a negotiable point. It will lead to Twitch losing users, from which it gains its monetary value.
