I think the point was that they are asking for $$$ by having a "Free vs. Pro" business model (i.e. people pay $$$ for Pro), so where does the need for a Kickstarter campaign come from?
That's not to say there is something wrong with it. It just seems confusing at face value.
I'm not really sure why the idea is such a foreign concept to the point where you need to insinuate that I think that Free software "falls from the sky" or some such nonsense.
That's a new one. How does someone getting making a living while developing open source software mean "everybody loses"?
You can, however, do it as a function of your work for your employer. Almost all of today's viable FOSS started like this, because it provides the financial security and moral support you need to bring a FOSS to maturity.
