Sharman Networks Ltd., the company behind the Kazaa file-sharing software, filed a federal lawsuit Monday accusing the entertainment companies of using unauthorized versions of its software in their efforts to root out users. Entertainment companies have offered bogus versions of copyright works and sent online warning messages to users.
Sharman said the companies used Kazaa Lite, an ad-less replica of its software, to get onto the network. The lawsuit also claims efforts to combat piracy on Kazaa violated terms for using the network.
