I feel what we need is not this, but rather a cultural change among the corporate consumers of open source. I'm arguing for this at my employer: that we set up a fund to support open source libraries that we rely on for our products, with a regular payout for products that we are using.

So far it isn't easy going: what reason is there for paying developers who already give us their work for free? Who do we even pay, if there are multiple maintainers? etc. So far I've come up with "goodwill" and "responsible citizenship" (i.e. maintain the ecosystem that sustains you), and I'm drawing a blank on that last question...
