> The article does point out exactly this problem, but glosses over the fact that most artists don't want to change to popular art. Only a few can, and most don't want to.

I don't think author hides the fact. It's plain as day that to make a living, you need to sell art which resonates with people. You can still find room to be creative within that constraint, but you can't ignore the audience.

Artists should quit the illusion that they can create whatever they please and expect the income to automatically follow.
