Oh! Yes, “Communities getting together and making their own broadband” does sound like a decentralized approach and I agree that it's worth doing and certainly shouldn't be outlawed. I didn't see allergic reactions to that - but maybe I didn't look enough yet.
This sub-thread seems to be about using StarLink, which I don't see as any sort of "decentralized" given it is literally global and in effect controlled by one billionaire so hence my question.
another decentralizedish community solution in nyc is https://nycmesh.net/ which I used for years and volunteered on an install. biggest issue with nyc and why I can't use it anymore is you need line of sight to a hub node.
