The interviewee didn't define monopoly by anti-competitive behavior.
> Is Amazon a monopoly?
> Yes, monopoly power is defined as the power to control prices or exclude competition. Amazon has the power to do both. But being a monopoly on its own is not illegal under the antitrust laws. Illegal monopolization requires both 1) monopoly power and 2) that the firm acquired, enhanced, or maintained that power by using exclusionary conduct.
