I thought the whole point of "raw data" was that it was, well, raw, and not edited "for public consumption".
You want a binary file with no idea of its format? We have no idea what has been given to them and who that have handed it to so they could check it out for themselves.
I would presume there's some back and forth going on about how to release what data and its formating. There could be for instant, a huge binary file with data for all pings of all aircraft for the birds field of view for x hours. Or there could be one that has only the data for that flight extracted.
Any decision they make will be criticized, and accused of a conspiracy, so they will most likely be taking the time to be extra careful with a decision that would normally be flippant.
