Scapegoating.
If that was a deliberate act by the crew - and I think that's IMPOSSIBLE - it surely backfired, inflicting a cost they'd never have imagined. Stuck on the ship for two months, essentially under arrest. Their personal property gone through. Their phones, their only contact with the outside world, seized. Their ship seriously damaged - maybe to be written off as a constructive total loss, and scrapped.
Their prospects for future employment, should the ship be condemned, will be slim. Who in their right mind would agree to such consequence, for a meager sum under the table?
All this is, is to find someone to blame, maybe to put the ship's insurer on the hook. Maybe for political or industrial reasons - blacklist the ship's operators or the complex system of registration, operation and book-ownership.
I don't think truth or fact is in any of this.
