I think it could be a great solution. I’ve never considered it before. That said there’s one sticking point for me:

Apportion payment to developers based on software use by paid users and the size of their contribution to that software.

That^ . That needs a lot more detail. If they provide solid details – details that most can agree on – then I will actually be on board with the solution.

I get the sentiment. Do you have an alternative way to pay people across the world anonymously?
