I think “attribution” might be more apropos than “advertising” when it comes to an artist’s signature. Of course the presence of an artist’s signature will advertise their authorship, but the signature’s purpose isn’t inherently trying to drive you to a website/patreon/whatever; it’s letting you know who put in the effort to make the art.
It is advertising, but it’s a good kind of advertising. I’m for advertising in this specific case.

I think letting us know who made the art is important because it lets Adam afford groceries, and that’s okay.
As the other comment says, attribution is not the same as advertisement.
