Your opinion on ethics of using limewire for mp3s?

I'm a limewire user and a reporter writing a story for the Ottawa Citizen about how music companies going after P2P servers due to fears of mp3-swapping is, some say, kind of misguided.

I'm looking for comments on user's views on the ethics of using Gnutella-like software for this purpose. Does it bother you? Also, are music companies justified in trying to shut down P2Ps (re: Audiogalaxy, Morpheus, Kazaa and Grokster law suits) if not all users are trading MP3's?

I'll need names and city locations please, in order to quote you.

Thanks.
