I found this overview of free software developers income quite informative: https://staltz.com/software-below-the-poverty-line.html
That analysis is using mostly *wrong* stats to study what does and doesn't need/get funding.
There's NO correlation between the potential value of some FLO software and the cost of development. We do *not* need to fund trivial-to-develop software even if it gets used by everyone on the planet. We *do* need to fund software that requires funding *and* provides real value.
