Lawrence Lessig claimed, however, that this decision made little sense from the perspective of copyright protection: "When Napster told the district court that it had developed a technology to block the transfer of 99.4 percent of identified infringing material, the district court told counsel for Napster 99.4 percent was not good enough. Napster had to push the infringements 'down to zero.' If 99.4 percent is not good enough," Lessig concluded, "then this is a war on file-sharing technologies, not a war on copyright infringement."
