Many open source projects have been widely used without getting any funding at all. In the last decade a group of bureaucrats have arisen who promote the notion that open source will not function without their gracious presence.
In many cases these bureaucrats destroy working projects for their own benefit (fame, power, salaries they would not get otherwise).
That isn't meant to say that funding is bad in all cases, but reflexively cheering whenever a new fund is announced is naive.
Widely used does not at all imply that they’re financially or otherwise sustainable. See the OpenSSL debacle which was at least partially caused by lack of paid maintainer time. It’s not like the lack of funding for large open source projects gets mentioned every time a major bug is discovered in one of those widely used open source projects (log4j maybe?)
A lack of money also means that the pool of people working on public good (open source) projects self-selects to those that have the money to do that - and that’s limiting the pool and input into those projects.
