I don't believe this is a realistic take on open-source. There's not a single successful modern OSS project that's not basically controlled by a single organization (or was not at some point in its conception). Control can take multiple forms: most of the time, it's directional to the project, since the roadmap of the company managing the project dictates what gets done. Sometimes, it's in the form of how you can use the project. The great thing is that you can always fork the project and create a version for which the new rules/direction does not apply. The challenging part is making that a project where active development is actually happening.
Certainly, there's things like the Linux Foundation that serve as places where projects can live without formal control by a single organization, but in practice, orgs that commit most of the code control things (for better or for worse - I'm not saying this is a good thing)
