There's a recurring talking point in The Discourse about "this is why you need to pay OS lib devs" that is not entirely wrong yet simultaneously seems to be missing the point in a rather profound way for many scenarios.
It's true that many important libs that a lot of programs rely on (another example would be libjpeg-turbo) are underfunded and lack for resources, but beyond that still is code that doesn't even want to try, and I don't see space made for that either.
To explain, I'm sort-of co-maintainer of the stb libs at https://github.com/nothings/stb. I say "sort of" because the way that originally worked is that Sean and I are friends and years ago Sean said "can I add you as maintainer to that repo in case something happens to me so it's not completely orphaned" and I said yes.
