Yeah, a union would be great, although I feel like that would be something that would have to come quite a ways down the road of ethical devs coming together. After all, not even the FOSS community agrees on what is ethical to give away and to whom.

Maybe a union is still the right term for the abstract 'coming together' I'm thinking of, since it's hard to imagine how they could go from a generic collective to a body that could actually make effective demands, but perhaps it's roughly the same process as getting a job-wide union off the ground.
