I think this is what a lot of people mean when they say that FOSS (and Open Source in general) 'lost' in the grand scheme of things. Sure, FOSS is running the entire show from sites to servers to databases to build systems to programming languages, but, whether or not you can actually see the code seems to hold little sway when the war is really over personal data and privacy. Who cares if I can see the tensorflow source code when the real danger is in the models these companies are building, which themselves are aggregated of petabytes of 'anonymous' user data. You'd have to open-source the data, too, to see how these businesses are truly run.
