Are you actually arguing that musicians should be into it only for the music and not get paid? If so I completely disagree and that's not my point at all. Musicians absolutely should be paid.

Software authors should also be paid. I'm just pointing out that there are some practical problems with it in the open source setting.

My ideal would be that essentially all software is open source, but everyone would also get paid. But I realize there are many reasons why we don't have that situation today.
