This is such a ridiculous accusation. Why do discussions about source-available models often turn into accusations of soliciting free labor? Why can't authors just provide access to source code, but reserve some or all of the distribution rights? It's their code, after all. Nobody is forcing 'the open source community' to contribute under the terms set forth; anybody who does contribute does so under their own free will, under the terms set forth by the license.
It doesn't always have to be a binary choice between open source and closed source, nor does it justify further accusations of "openwashing."

And? Yes, we're all acting out of our own free will. The owners of Winamp decided out of their own free will to release their code under those terms, and I'm criticizing them for trying to take advantage of people also out of my own free will. What's the issue?
