Vitalik's article "We should talk less about public goods funding and more about open source funding" points out that the word "public goods" is a century old. In digital ecosystems, especially decentralized ones, public goods are extremely important: in fact, there are good reasons why the average good one might want to produce is a public good. Open-source software, academic research on crypto and blockchain protocols, open educational resources, and more are all public goods. Vitalik believes that there should be less talk about public goods funding and more about open source funding. Shifting the focus from "public goods" to "open source" also seems to be the best practice. Open source should not mean "as long as it is open source, it is equally noble to build anything"; it should be about building and open sourcing what is most valuable to humanity. But it is already well known that distinguishing which projects are worth supporting and which are not is the main task of public goods financing mechanisms.
