Why does LimeWire exist if it allows people to engage in illegal activity?

A p2p server is not illegal, which is what limewire is.Limewire has numerous things you can download, not just music. Downloading and sharing copywriiten music is illegal, however limewire is not neccessarily meant for that, although its obviously what it is used for. It's kind of like this, its not illegal to have a camera, and its not illegal to have naked children in your house,(if their your own), but if you video tape your kids naked and sell it, then its illegal (child pornography). I know that's a bad example but its all I can think of for now. Limewire itself is not illegal, however, its up to you to decide if your going to commit illegal acts with the software.
