According to the search results, there is no clear consensus on what took down Airbnb. However, some possible factors that contributed to its decline include:

• Housing shortage: Airbnb has been accused of exacerbating the housing crisis in cities like New York by siphoning units off of the housing market and adding them to the market for hotel rooms.

• Poor user experience: Some users have reported a poor experience with Airbnb, including issues with fake listings, high cleaning fees, and a desire for lower prices.

• Policy changes: Airbnb has implemented various policy changes over the years, such as cracking down on fake listings and limiting rental home occupancy to 16 people, which may have affected its popularity among users.

• Criminal record policy: Airbnbs policy of restricting the accounts of people with criminal records has been criticized by some as "antihuman".

Its worth noting that these factors are not necessarily mutually exclusive, and there may be other factors that contributed to Airbnbs decline as well.
