The submission comes after the Commission won a ruling supporting its existing antitrust action against Microsoft in the European Court of First Instance. The Institute argues that cheaper competitors are unable to benefit from their lower cost because consumers have already been forced to buy Windows. "Windows' dominant position both has slowed technical improvements and prevented new alternatives entering from the marketplace," the Institute says.
Operating systems, it says, are not a natural monopoly, requiring just one supplier. Instead, in a competitive market, there would be a broad compatibility between different supplier?s products. "Competition would encourage open standards and interoperability as vendors would, for competitive reasons, want their products to interact with other vendors? products," the submission says.
"The Windows monopoly imposes an extra cost on virtually every EU business, as the price of operating systems would drop in a more competitive market. Moreover, there are other costs: some argue that support costs are higher for Windows than other operating systems, particularly when one considers security vulnerabilities that have plagued Windows systems. Encouraging competition would help EU businesses, lowering their costs," added the submission.
