You can not get an competitor, because US goverment is not enforcing the antitrust law.

In an market economy the market can make efficient decisions about investment, production, and the distribution of goods and services to consumers, guided by price signals created through the forces of supply and demand. But the market can not prevent companies from forming an oligopoly or a single company winning the competition race and becoming an monopoly, only the goverment can.

"In 1999 a coalition of 19 states and the federal Justice Department sued Microsoft. A highly publicized trial found that Microsoft had strong-armed many companies in an attempt to prevent competition from the Netscape browser. In 2000, the trial court ordered Microsoft split in two to punish it, and prevent it from future misbehavior; however the Court of Appeals reversed the decision and removed the judge from the case for improperly discussing the case with the media while it was still pending. With the case in front of a new judge, Microsoft and the government settled, with the government dropping the case in return for Microsoft agreeing to cease many of the practices the government challenged."
