Cuban wants to ban online, less biased (he wants them to be biased towards the Mavericks), reporters:
The most obvious flaw in Cuban's suggestion that he has the power to restrict access for independent, online media and replace them with his own reporters is, quite simply, that he does not have such power. Why? Because the Mavs, which he repeatedly referred to in the CNN interview as "my business," are not his business. Cuban is a willing partner in a cartel of 30 businesses known as the NBA, which enjoys, among other competitive advantages, partial exemption from U.S. antitrust law.
The Mavs would not exist without the NBA and Cuban's 29 partners, and wouldn't make much money without the federal exemption that allows NBA teams to pool television rights on network TV without antitrust scrutiny. Cuban has agreed to abide by anti-free market rules like this and others, such as the salary cap and revenue sharing, to enjoy the many benefits of owning a professional sports team.
