Today, MP3tunes’ CEO Michael Robertson sent out an email to all users of the online music backup and place-shifting service MP3tunes.com, asking them to help publicize EMI’s ridiculous and ignorant lawsuit against the company. EMI believes that consumers aren’t allowed to store their music files online, and that MP3tunes is violating copyright law by providing a backup service. (And we’re not using a euphemism here—it really is a backup/place-shifting service and not a file sharing site in disguise.)
