My interpretation of the article is that the entire reason this person created this was because the artist had objected to being in a generative model. When the artist was removed from the popular generative model, this person created a model/tuning specifically to put the artist back into one, and distributed it. They seemed to do this well aware that the artist didn't want to be in a generative model.
That sounds aggressively adversarial and abusive, and so the quote above sounds disingenuous.
Consider the analogy of a bully who is hitting a victim, and the bully demands that the victim ask the bully nicely to please stop. Humiliating the victim, and making the victim acknowledge the bully's power over them. Also, this is only after much damage is already done to the victim. And, in this case, after the bully has called over a mob to also beat the victim, and knowing that, even if the bully stops, the mob will continue.
The person in this case might not have the self-image of a bully, but is instead thinking of it as the usual Internet get-out-of-jail-free card: such as when you post someone else's content, when you're pretty sure they don't want you to, and without even trying to get permission, but you think it's all OK if you say "I'll take this down if they ask me to". (Related: The YouTube copyright violation disclaimer "I don't own this! All rights to the owner!", maybe even referencing the "All rights reserved" of a traditional copyright notice.)
Wherever you stand philosophically on copyright and related matters, and whatever jurisdiction and economic conditions you're under, it's maybe also helpful to consider the bullying question. One can stray into that accidentally, and that's harder to justify.
