Let's take a musical analogy - a 'group' group. With a four piece popular beat combo the royalties go four ways, it is all viable as a business. With a larger collective or an orchestra the money gets a bit tight - it goes forty rather than four ways.

But, this is something my internal dialogue says whenever I hear a musician talking about money (and where there share is...) - 'But you are in it for the music, right?'

This musicians seem to forget, they become businessmen and think the value is in the magic of their work and they should be paid for it. I wish they kept music as a fun thing rather than something they 'only do if paid' and for them to see hiring venues and doing tours and selling merchandise as what they need to do for money.

So, analogy is different to reality, however, we must remember why we do stuff for Open Source. Instead of looking for T-shirts and venue tickets to sell, we need to have real world needs for the Open Source code, to work on those problems and get paid for them using and contributing as required to the FOSS projects. As for expectation for pay from the FOSS project (rather than the day job) it should be 'you're in it for the love of music, right?'
