Do you seriously believe that a company like Sony would do something like this?
The domains were registered using "Domains by Proxy" so the whois information is anonymous. All we know right now is that someone registered the domains and they are forwarding to the official BDA web site, why or by whom we have no idea so I think it's unfair to call out Sony before the facts are known. Anyone that wanted to could have registered the domains and then simply started forwarding them to blu-raydisc.com.
