This is a nice start for allowing sending "coffee money" between persons. If however you want to drive Serious Money into actually funding OSS projects please remember this: While virtually no company has a donations budget, almost every company has a $$$ marketing budget.
Please let me give you some of that money that would otherwise be spent on blue pens with logos and endless display ads to GitHub projects. I'd be happy to drive $xxK/mo to open source projects my company depends on or that are simply being used by an audience that aligns with our own. To sell that internally, I need (as in, I would be laughed out of the room to propose it without):
- My sponsoring company logo on the GitHub project page
- UTM links and all that jazz to attribute traffic and campaigns to the specific projects that we sponsor
See https://webpack.js.org/ for a good example of a successful sponsorship program. Literally the biggest hurdle remaining for BigCorp to sponsor something like Webpack today is selling your boss on "Patreon" and "OpenCollective". But if you just increase our GitHub budget by a few K/month, AND the marketers get attributable traffic to boot that we can point to, well that's an easy sell!
