What makes something "the most useful software in the world"?

There's a bunch of useful software which isn't run that way: Microsoft {Windows, Word, Excel, PowerPoint}. The software which runs Facebook, Google search, and Google's YouTube. iOS.

How much does Google Chrome development "resemble anarchist, communist ideas"? Or Android, for that matter.

Minix is in every modern Intel processor, but I also don't think it was developed by the ecosystem you describe.
