There is very little the anchored ship could have done to avoid the collision.
The ship underway should have a bridge team, especially when transiting a busy sea route.
The ship at anchor should have a watchkeeper to record regular bearing sightings to check ship is not dragging its anchor.
But the ship at anchor should have DSC'd the other ship and advised them at about 5 mins out, latest and then again on Ch16 if no reply. I suspect the lack of log or call will be enough for the at anchor vessel to be charged.

But didn't the colliding ship change course just before it hit? I can understand a closing ship with a constant bearing would generate a warning on the net, but a late change of course would be tough to mitigate.

No - in this thread the AIS track was presented at a scale of about 100m. What you saw was the bounce and effect of the anchored ship on the impacting ship. Both ships AIS would have shown a collision risk for at least 10-15 mins and CPoA would have been close to zero or just a few meters.
when I cross the channel I usually do a courtesy call at 10 mins if a cargo vessel has a CPoA of less than 200m. A lot hope you will adjust course, but will usually reply that they will adjust speed. The benefit of a DSC or CH16 call is it will be heard by others and the DSC call is logged.
