AirBnB absolutely removes housing from the one rental market that matters - long term rentals. This is quite easy to see, as well as its influence on supply and thus pricing. In 2020 the number of long term let's available in Dublin doubled thanks to tourism shutting down and landlord switching. Sadly that's likely all been lost now.

Short term lets are nowhere near as important as long term ones, especially vacation rentals. They're actively harmful often, especially with the way AirBnB takes supply from the long-term lets.
