With that out of the way, lt me explain some uncomfortable axioms I use since many years.
#1: FOSS (Free and Open Source Software) needs stable funding. Making money with FOSS is not only perfectly fine, it is needed IMHO to keep FOSS alive and kicking. I don't want FOSS to be a hobby of the privileged that can spare time and energy to work on it. I want it to be sustainable and a source of income for those that do teh work.
