LimeWire was a free peer-to-peer file sharing that started in 2000.
On October 26, 2010, U.S. federal court judge Kimba Wood issued an injunction forcing LimeWire to prevent "the searching, downloading, uploading, file trading and/or file distribution functionality, and/or all functionality" of its software in Arista Records LLC v. Lime Group LLC.
I personally do not think this is fair.
