It's the same with every bureaucratic agency: just pass a vague "act" in Congress wherein the legislators say "do what you want, as long as you pinky-promise you have a good reason" and somehow that allows such agencies to exceed the authority vested in Congress itself?

Well, hopefully that phenomenon has had a brake-pump with the SCOTUS ruling on the EPA. But even so, big tech is the same problem except even more radical since it also represents an epistemological crisis.
