Have you got some references for that? The digital nomads seem like a small enough group to not matter in the grand scheme of things. I'd be extremely surprised if they impacted the Airbnb bottom line at all.
Pretty sure they don't have any references... can't even know that accurately from any public filings. However, I do think there might be some correlation on longer stays (maybe some % of those are digital nomads) from statements from Airbnb leadership where >1 in 5 stays are greater than 28 days [1]. That statement is from 2021, so I'm curious where it might land today.
Different person here, I make no specific claims, but it seems obvious AirBNB is biased. Their model is helped by people with money being able to travel frequently. Of course they would say rooting workers with disposable income to one location is bad.
