Not from principle. Marketing is hateful work and almost necessarily anti-art, so I don't care. Of course you can do it badly (for example, unironically advertise to an artist audience with terrible slop illustrations).

I don't see how replacing a photographer with AI for advertising is considerably different from replacing a photographer of a nature scene with AI. Is it just "AI is okay for commercial uses"?

But it seems more extreme when the AI is recreating the art you are considering buying.
