For those speculating intensely over the style of damage to the tail - you might want to see the following photos of the tail recovery from the Java Sea.
It wasn't lifted on board carefully, as it should have been - it was dragged aboard the recovery ship via a low-mounted winch with a horizontal winch cable.
This technique shows the Indonesians are inadequately prepared for wreckage recovery, with a shortage of adequate marine craneage, and they care little about preserving the wreckage in "as-found" condition, to be able to figure out impact forces, angles, speed, etc.
They are obviously relying on the FDR to provide all the info they need as regards the flight path and impact attitude.
