A controversial DMCA judgment is being considered as an exception to their extensive anti-piracy policies.
According to ArsTechnica.com, the exception "seeks to give gamers the right to modify games with abandoned online
servers in order to restore online gameplay and functionality." Both the ESA and MPAA are fighting it, calling it "encouraging... unlawful reproduction and distribution of infringing content."
Maybe you shouldn't have abandonded the server and left a hole in the lives of your fan-base then.
The Electronic Frontier Foundation (EFF) suggests a six-month period of server inaccessibility to determine true abandonment, seeking a middle ground to protect both developers and ethusiastic fans.
