Your point about donations and grants is a good one. Working with us does not mean maintainers have to exclusively use contracts to make money. Making open-source more sustainable will definitely require an aggregation of resources. We’ve learned from maintainers that donations can also have unintended consequences and create certain levels of expectations from the individuals and companies that make them. However, for some projects the donation model can work well, so we definitely encourage maintainers to also accept donations in these situations. Vue.js is a perfect example (https://vuejs.org/).
