I'm with Wiley on this one, albeit from the other end of the microphone.
If I was ever in a situation like this, I think it would be hard enough to cope afterwards without having to hear yourself vainly trying to call an aircraft not knowing what has happened to it. The same happened with Egyptair as well.

I don't think morbid secrecy is the problem, its the morbid fascination that some have which is being fuelled here by the media. CVRs and ATC tapes are recorded to assist in solving incidents not for broadcasting to the public. How does this help solve anything?
Transcripts are OK because they have de-personalised things a bit, but not actual recordings.
What benefit does it have to the public? None.
Is it news? I don't think so.
People can imagine what went on on the flight deck without having to hear it.
