The news media are making a big deal that "the pilot" acknowledged a frequency change some minutes after the ACARS was disabled.
However, they're not making a big deal that he did so with "roger that", (or similar), a phrase that many have said was unusual in the circumstances.
Has voice recognition proved that it was the Captain's or FO's voice that made that acknowledgement? I very much doubt it. It could have been - and in my opinion, quite likely was - someone other than either of the operating crew.
Blaming one or both of the pilots is too convenient - it absolves the authorities of many very uncomfortable and inconvenient implications that have the potential of gutting passenger bookings and costing airlines enormous sums in increased security procedures.
I for one am not buying it.
