Percentage cut? I think the better title would be Patreon for Open Source (which is also itself used for Open Source, e.g. Vue.js). Seems like a huge win for Tidelift.
I would like to have just one amount per month that gets withdrawn that I don't have to think about any further. And that just gets distributed over projects. With the idea that a lot of micro payments make more than a few big payments.
The problem with indiscriminate is that there are many, many, many OS projects out there. You need some curation, and that opens a can of worms. Maybe they could allow people to share and use lists?
This is complementary to and different from a donation model.
