EMI, Sony, Universal and Warner have many years experience of trying to sue people away from P2P networks. In Spain they have turned their attentions to Pablo Soto, the 30 year old creator of the Blubster, Piolet and Manolito file-sharing applications. They say his software is "unfair competition" for them, and are in court this week, suing him for $17.8m.
