I'm upset, after using the platform for a decade, that they remove negative reviews of properties. I learned this recently. That included some of my very tame and reasonable reviews. Makes me want to short the stock when it IPOs, after its initial run-up out of vengeance.
Another dark pattern is hiding the price until you are nearly booking the place. Most people want a cheap stay close to where they need to be, so they look on the prices on the map, which fail to include fees which can be all over the place depending on the host.
For ebay they did not take a cut of the shipping cost(typically their cut was around 10% of the final sale of an item) so sellers would list items at rock bottom prices but with shipping like 5x of what it should be so they could receive a maximum amount of money. I assume airbnb does not take a cut of cleaning costs?
