From the CNBC article it reads
"Cathay Pacific, for its part, said it has never installed such devices in its IFEs.
“Our inflight entertainment systems do not have any cameras, microphones or sensors to monitor passengers, nor have they in the past,” it said in the statement."
And I am pretty sure we only have those camera outside the flight deck and they probably do not retain footages. This whole news was about our policy update, speaking of a provision in a policy. But some how they work out that cx have admitted that they are spying on people. Must be a slow news day.
