> So if you're an artist and don't want your style to be used in an AI product, all you have to do is changing your name that includes a variation of controversial leader names (xi, adolf), or slightly offensive name (dick, gore)?

Nope, that doesn't stop models from being trained on your art. It makes it somewhat more difficult for people to prompt specifically for your style, but your art still influences output, and there may be other ways (e.g., titles of specific works) to deliberately and specifically evoke it in particular.
