My suspicion is that SpaceX and the ESA disagreed either on: 1/ the position of the SpaceX vehicle (ESA may not trust the SpaceX position data) 2/ that they disagreed on the probability of a collision (ESA thinks it's 5%, SpaceX thinks it's 0.005%) or 3/ they disagreed on whether the probability of a collision was worth moving for (eg, ESA thinks you should move for a one-in-a-million shot, SpaceX disagrees). I recall someone saying that SpaceX did share ephemeris, but I can't find a reference. Maybe I dreamed it.
