> Anti-trust lawsuits don't require an absolute monopoly. It requires proving that a company behaved anti-competitively

Also, having a monopoly (even an absolution monopoly) does not automatically mean you are violating antitrust law. You had to do something anti-competitive to get that monopoly or be doing something anti-competitive to maintain it.

The easiest way to think about it is that US antitrust law is about preventing monopolization, not about preventing monopolies.
