That's entirely up to the artists though, and plenty choose to publish their work rights-free. However, they can't earn a living off of free or charity-paid-for music. While I'm sure there's a way to make money off of rights-free music (I mean you can still publish your albums, get on Spotify, do concerts etc), it's going to be similar to open source software - you can't compete with free.

Most musicians, even really big ones, make the vast majority of their money from performing. So this wouldn't impact them much at all.
