Correct me, when I am wrong, though my memory says, there were other reputable airlines (SQ ???), also overflying Ukraine, on the same day. QF/KE were already avoiding the Ukraine airspace. And, let us be realistic, how easy is it, to judge on your own, whether an airspace at the other side of the world is safe to use, when the local airspace "owner" gives a green ? This would be a lot easier to determine for airlines, hosted "around the corner".
Not to say, the JIT has investigated this whole and never did come up, that additional info was available for Ukraine or the airlines, that the airspace above FL250/320 would be unsafe. Given the "unsafe airspace" is one of Russians defenses, it can be expected, the JIT did focus on this subject. The general no-nonsense, no cover-up approach Dutch people tend to have, makes it also not likely, information around this subject is kept secret.
UkSATSE should have closed the airspace to the top.
