Not sure how the CVR recording was played at a cocktail party but obviously misuse/mismanageent of acquired data (on this occasion for entertainment) happens in all industries.
There are normally rudimentary interlocks to stop Johnny technician downloading the CVR data, for the hell of it, with the CVR in situ. These can obviously be overidden with the right knowledge but it still requires more than just hooking a laptop and cable to the CVR. To say it is there for all to witness is a little dramatic.
I agree about the part of pilots "magnaminously permitting" the CVR, or rather they did not do so. Like most avionics developed and then implemented in recent years, they were mandated by the authorities.
