Hello Morgan. I would like to agree with you, but, why wasn’t the data released on day 1? Not releasing the data should result in a lawsuit from the families especially if we find out that anyone survived but died of exposure because the data was not released.
Boeing isn’t going to release something unless they have to or need to. They would have a strong defense in saying this service was not provided or paid for. What I mean is, they would have it among all the data they have anyway but they would not look for it unless necessary.
In the long run that may not be totally true. Boeing would be wise to cover themselves against possible liability or actions against them. That means having the data if it’s ever needed by them but not releasing it unless requested.
I'm sure Boeing would provide all the information it had (if it had any that was flight-specific, not saying for sure it did), pronto. Not that the information would be delivered publicly, just that any entity involved in the loss would get the information, especially the airline and the national authorities.
Boeing is always in line for a lawsuit on a crash event, even if the primary cause is traced back to pilot error. "Could have designed the aircraft to make this error less likely," etc.
