As an expat living in the Netherlands I've seen this up close, but in most part it seems this is temporary. Many properties that were previously Airbnb-d were put up for rental, but only for short contracts of a year or two at most. This leads me to believe that many of those listings hope to return to Airbnb once tourism and the like picks up again.
That's what seems to have happened in Dublin too. Last August saw a doubling of long-term rentals, most in the areas most hard hit by AirBnB. I don't think it's lasted, given how bad things currently are here, sadly. Something really needs to be done to move them and keep them on the long-term market where they belong.
Yes, they are probably just waiting for the pandemics to end to go back to short term.
