I wasn't thinking about companies at all. Companies tend to only contribute to well-known projects, which leaves a very long tail.

I'm thinking about the far more random regular people using random projects that may not be that popular. Like I just did a rough count of the OSS apps on my phone: 60+. Of those there are 5 that I can immediately think of improvements that I'd like. One of them I've actually made improvements to already because it was a dead project that I really like and so had to revive anyway. And I used Claude to work on it as I'm not a mobile dev; been planning to republish but haven't gotten around to it. I won't bother to check my laptop but there's even more there.

Now imagine if I (and others interested in those projects) could contribute to small funding pools for various projects of interest, with the assurance that said funds go to that feature/fix which is of interest or gets refunded. I think that'd result in the general OSS support needle being pushed that much further over time.
