Highly skeptical of undemocratic organizations whose founder immediately talks dismissively of government programs. Comments from OP aren't helping either.
Just another Silicon Valley bro that wants to be in-charge of something with zero democratic control. Very typical in the current environment, which is why it should be soundly rejected.
Our bylaws are pretty standard:

What part of them is "undemocratic" in your view?
What government programs in the US are stably funding open-source developers? I think most government-funded open source projects are very gunshy about looking for new funding because of the Trump administration completely politicizing grants and funding. I would not want to have to sign an anti-BDS pledge to get my open source project funded, and I would imagine that goes for many people in the community. Also, what "dismissive comments" are you referring to? The only one I saw was "Government support won't work for OSS at scale — it's too globally decentralized". Which is a fair criticism—open source projects are incredibly globalized, and getting e.g. New York State to fund an open source project that has contributors from Ukraine, India and China is a headache I don't think anyone would want to try and go through. There's just no benefit to the state administrators to fund that kind of project—they want to support parochial, home-grown projects with local ties.
In undemocratic organization wishes to fund my development of OpenStreetMap-related software I would gladly take money.
As long as it is not something outright evil like theoretical Gazprom Open Source Fund or something similar.
The project has involvement from people who have spent decades dedicated to these ideas — it doesn’t seem like a vanity project or a play for control. The most cynical view is that it is beneficial to the OP because it provides access to potential investments, which, sure, isn’t a pure philanthropic venture, but that seems a pretty small price to pay. The people involved are the people you would surely want running this project.
