It seems unsustainable and mixed up to think no one should ever use non-FOSS options for anything.

Maybe that would be the case if we were in some post scarcity perfect society where no one needed income, and all devs were just doing it for self-fulfillment, but I can't blame someone for wanting to make income off of their work. Especially if they seem like a reasonable person, wanting reasonable amounts for good work.

Isn't supporting a smaller dev a good thing? I mean, this guy got screwed over by reddit fucking up his income.
