That's true, but at least all these places were kept unharmed and less touristic before airbnb. Each island's tourism was almost limited around hotels and established rental houses before. Airbnb opened up the gates for that extra income for anyone having more than 1 property, these side businesses, building, renovating, managing, cleaning, selling around airbnb. And if you are a rich foreigner, you can buy properties everywhere in the world and keep making money from that local tourism.
