The United States Department of Justice, along with the Attorneys General from 15 states and the District of Columbia, filed suit against Apple for violating Section 2 of the Sherman Antitrust Act, the federal law that limits the power of a company with a monopoly.
According to the suit, Apple has made it difficult for developers to expand the capabilities of the iPhone, made it difficult to leave the iPhone, and generally made the entire smartphone market worse as a result, among numerous allegations.
