In a free society, all information of public interest must be free
In this day and age, it is important that as many sources as possible can have a crack at interpreting data that is of public interest. Accidents where people are hurt or die and financial interests are at stake (i.e. all accidents) by that very definition thus are of public interest.
This is not about armchair investigators or morbid sensationalism of the public. But even when there are a few of those, what do you care? What's important is that there are checks and balances *especially* when accidents occur in parts of the world where the facts are often obscured by convenience. Just look at them heave the tail section on board of that salvage vessel. What about the lack of post mortems on the bodies found? This is an absolute disgrace and a joke of an investigation thus far.
The flight deck during critical flight phases is NOT a closed office as much as anyone cannot send whatever they please via their employers email system. It will be read and you will be fired if you engage in inappropriate conduct. And there's nothing wrong with that.
I am of course assuming that there are no airlines left unfamiliar with the concept of a sterile cockpit, and that anything private said outside the sterile phase is not made public.
A big ask, perhaps. But certainly in line with long established office rules in the majority of the world.
