There is a lot to say about this, but surprised I am not. Actually strange it took this long. Though it is of course highly unfortunate for the passengers who are now trapped all over Europe, supply simple had to be come down at one point. So perhaps next year we will see one million less empty seats flying GOT-ARN :-)
Anyhow, if SAS decides to give some kind of "rescue-offer" to the stranded passengers they will at least be familiar with the quality of the onboard service since their outbound leg... hehe...
