Well, neither was Standard Oil by that definition.

Of course, we already know how to solve the problem of companies having too much leverage due to owning too big verticals - namely to break them up. Not to institute everything-goes rules.

Standard Oil controlled over 90% of production and nearly that percent of final sales.

Courts have never as far as I can find used antitrust on an actor controlling a market at the low level Amazon has here. Can you find such a case?
