Praticamente secondo alcuni adesso tutto quello che posti diventa di "proprietà" di facebook che può utilizzare le tue "opere" a fini commerciali.
ovviamente il problema non si pone per la marea di stronzate che vengono postate, ne per le foto a culo nudo che metto su facebook, quanto per quegli utenti che sono soliti usare facebook per divulgare loro opere (esempio classico le fotografie artistiche). c'è da approfondire meglio, sopratutto perchè ancora non è chiaro se queste modifiche sono retroattive o meno
