I have done a fuck ton of open source stuff, but only a small fraction directly makes me money.

That said I've probably done as much work or more that is proprietary, probably more. I dont feel bad, I feel there should be a mix of both in the world.
Even now as I am spinning up my new company (we recently got funding) I am trying to decide the balance between the two.
