I think we're getting somewhere now. The solution could be to fund the developers of open source software, actively paying them to implement the desired features that otherwise don't get picked up (while maintaining good quality and their continued ownership over the software). Micromanaging them as employees wouldn't work.
I agree with your idea. I'm working in Open Source. How much money can you send me please?
The above statement of course raises more questions than answers;
A) you believe Open Source should be funded. Are you willing to be a funder?
B) do you believe me when I say I write Open Source? (You shouldn't, I don't)
C) since you won't be managing this project, can I assume you'll just hope the feature you want will materialze at some point? In the form you are hoping for?
D) will you fund "any" Open Source, or only the OSS you are using? Or want changed?
