There are two problems there:

One is that not all open source developers accept payment, this is accurate, we have come across some that refuse to be paid for their work and not everone has the money to pay for it.

This forces, we believe, people back into the freemium etc model. So really there don't seem to be a lot of good solutions here, which seems to go against the original post.

Either folks somehow pool together to have enough resources to pay open source devs, we put up with whatever they decide to do, we create a new movement focused more around what the community wants or we go back to corporations, most will probably choose the latter as there's less tension there.

Something to think on.
