Corporations are just groups of people. Pure grass roots "We collect the money, anonymously in cash shaking a bucket at our annual fundraiser" does not work at this scale. Even Zig, which I'm guessing is about as far away from "It's all just owned by an inhuman corporation" as you could ask for, does have big ticket corporate donors. So does ISRG (Let's Encrypt) or the EFF.

Venture Capital is a bad fit, that's the conjecture here. VC funding for infrastructure is a mistake because that big pay day won't happen if you did it correctly. That doesn't make VC inherently bad, or projects like Linux inherently defective, the claim was that it's just a bad match, like how an Irish Stout doesn't pair well with a subtle tomato and angel hair pasta dish.

The funding assertion leverages the re-definition of “community” in “community funded” and relates to why all those big projects offer CE or Community Editions instead of calling it free or open source editions.

Enterprises are willing to take a look at free, but "community editions" are clearly for peons, not the big boys, so they license the commercial edition. It also productizes a subset of licensing rights in contrast with the commercial licensing rights.

In any case, in today's common parlance, community doesn't mean ICs and IC donations. It can, but it's been mostly co-opted by corp donations, which are still donations and not VC.
