Consumers rely on Amazon. So why did the FTC file an antitrust suit?

U.S. regulators and 17 states have sued Amazon over allegations that the e-commerce giant abuses its position in the marketplace to inflate prices on and off its platform, overcharge sellers and stifle competition.

The lawsuit, filed Tuesday in federal court in Amazon’s home state of Washington, is the culmination of a yearslong investigation into the company’s operations and one of the most significant legal challenges it has faced in its nearly 30-year history.

The Federal Trade Commission and states that joined the lawsuit allege that Amazon is violating federal and state antitrust laws. They are asking the court to issue a permanent injunction that they say would prohibit Amazon from engaging in its unlawful conduct and relax its “monopolistic controls to restore competition.”
