Instead of taking a CRJ/A320 rated pilot, they now have to pay for 2 type ratings per pilot instead of 1. Unless they magically found 6 guys with CRJ rating and 0 hours on type.
There are younger experienced pilots out there who have been working abroad, waiting years to get their chance with SAS and who would not hesitate to join SAS without complaining about current conditions offered.
I don't know how that is thinking about the future, but we are reaching a level where nothing from SAS can surprise you.
