A true artist does art whether it be music, painting, photography, drawing, video editing, etc for the passion and trying to influence other people or even change someones life. A true artist doesn't care about money. Someone whos in it for fame and money isn't an artist in my book, they're just someone who abuses art for their own gain meaning they lack respect in art. I respect artists more if they're passionate and strive to be influential with their work to change someones life even if the artist isn't very good at what they do.
Not exactly sure if I answered the questions right but it was worth a try.
I suppose that can be tied in, eg: is an artist's message relevant if they clearly show they're just in it for the money. But the topic is more about whether you can separate something like Woody Allen's personal life from his movies, or Roman Polanski's, things like that.
