Even if they are just in it for the money, artists who commercialize their work still have to make art that other people want to see, otherwise they wouldn't get paid. Besides, art costs money to produce, and good artists deserve to be rewarded for their labor.

Just look at summer blockbusters or AAA video games. Corporations spend millions of dollars to produce them and market them, and a lot of them are pure trash, but the good ones still have a lot of artistic merit. Is Spider-Man Homecoming less authentic or less artistic or whatever just because it makes a lot of money?
