bearfoil, it is documented that AirBus was frantic with the coming air show. I presume they were demanding a release to show their aircraft is not at fault. That is about all that the release shows. The aircraft did what it was told. (It obfuscates by not showing any definitive data that might indicate the aircraft supplied the pilots with inadequate information.
The release was made.
Somebody lost incentive to leak.
Was it the victim's families? Was it Air France, whose pilot was shown in a poor light absent a "why" in the data implicating training or aircraft data or aircraft data or presentation? Was it Thales? Was it who?
Follow the money says it was AirBus.
And of course, that is purely circumstantial evidence. Are there other candidates for the leaks?
