Perhaps I'm misunderstanding the original question, but the assertion that anybody is hijacking that particular prefix seems false.
Furthermore, that exchange prefixes may often appear to be anycast is not unusual. Those prefixes are often originated by multiple disparate networks who are connected to the exchange. In a lightning talk I did at NANOG 41, I talked about mapping peering relationships at exchanges. When I noted that these prefixes are often announced by exchange participants, Louie Lee explained that some of his participants often announce the space to their transit customers so that monitoring and troubleshooting tools don't cause confusion (e.g. traceroutes).
