Moz/Linux/BSD probably qualify. None of them would be possible without some kind of corporate support. FreeBSD is probably doing the best, but even for them they need corporate donors[1] Linux absolutely is carried to a large part by companies employing people to work on Linux. Mozilla needs to find income to pay its own employees. All three are slightly different models, but all three make it fairly clear that you can't cut all ties. As for the "what do you mean" part, "obtaining money via capitalist endeavors related to the project so non-affluent devs can actually afford to work on the project" is probably a good enough definition. In comparison, Signal is small - and even it can only make it because an extremely affluent person (Brian Acton) carries them. It's not reproducible for larger projects.
