You're missing some in between cases there. Free software developers fall into 3 basic camps: * Niche done by amateurs * Corporate funded development * People not being paid to work on free software but contributing to free software because it benefits the company they work for. I fall into the third camp. The company I work for would never send me to FOSDEM and don't pay me to work on OSS but they recognise that me doing so benefits them.
