Discovering new settings that I was opted in to without being asked does not scream good faith.

Separately, their help docs are gibberish. They must use this phrase 20 times: "content is not used for training generative AI models outside of your domain without your permission." Without telling you if that checkbox is that permission; where that permission is set; or indeed, even if that permission is set. From reading their documentation, I cannot tell if that checkbox in gmail allows using my data outside my organization or not.
