Re: Open source stuff should be free ...
It is free. Nobody is paying to use Babel JavaScript.
But if you want the project to survive, you need to have people willing to give their time to that, and it is simpler and easier to attract developers if they get a financial incentive out of it - especially if you want the good ones to work full-time.
That being said, I'm sorry but $11k a month is not the kind of incentive I think is justified for an open-source project. Up to $4k could be justified, following the amount of work the developer contributes, but I think that is pretty much the high bar.
It's Open Source. A living wage, yes, but if you're in it for the money, go back to being a company drone. Either that or create a startup and go hit venture capital.
