Freewire is just LimeWire + some minor changes to the GUI + SHOW_ADS set to false in GUIMediator.java.

They didn't make a single change to the underlying core. I doubt FreeWire will have ANY advantage over LimeWire, except that you cost LimeWire money from advertisement-revenues by using it.

Since LimeWire is GPL'd it's completely legal to create a fork and it's your decision whether to use it or not.
