Mastodon

I think it's one more incentive not to use mastodon.

Whats more is this: People who sign up to work on a FOSS project should have 0 anticipation, ZERO ANTICIPATION of being paid for their work on that project.

Start a consultancy around it? Sure. Charge to host instances? You bet. Combine those things with other value adds? Certainly. A patreon to facilitate a living while working on FOSS code? questionable. Insist on payment (that's patreon, people) to push your FOSS contributions to the public? Sorry that is NOT FOSS.

Expect to be paid for FOSS contributions? Maybe you should look up the definition of FOSS, then maybe do something to experience the community. It's about creating and donating value to the community, for the sake of that community, not self enrichment.
