Automation and production efficiency isn't what people mean by "economies of scale", though, especially in relation to antitrust. When large companies make gains from "economies of scale" it's almost always because they've attacked margins, usually by wielding enough power they can convince suppliers to make less money, sometimes by replacing other parts of the vertical market by doing things in house. If you think about the tech giants, they're not making gains by automating more production. They're buying up fiber, building their own chips, creating their own shipping companies, etc. They are big enough to alter most markets in ways that are favorable to them.
