I live in Lisbon. Over 80% of housing units in the historic Alfama neighborhood are now vacation rentals. This is the most historically Portuguese neighborhood in the capital. It was the only neighborhood to survive the earthquake in 1755. Fado was born there.

Yes, it's a failure of government policy, but I don't think it's hyperbole to say that AirBnB and its ilk destroyed that community. That is, assuming you define "community" as a group of people and not a group of buildings.
