I strongly hold the belief that, for the long run, the success of open source depends on establishing a profitable business model that rewards people like yourself who put their hearts into it.
There is a difference between "profit-driven" and "spending untold hours getting very little in return while some of the people using this are literally some of the richest companies and people in the world".
I am not at all money-driven; my current income is about €600/month, which is not much but a sustainable where I currently live, and in return I can work on open source/free software as I see fit. It's not what everyone would choose, but for me, it's good trade-off, right now away.
I wrote a bit about this over here last week[1], but I think we really need to think more about money instead of treating it as the devil.
