Replace "airbnb" with "microsoft" and see if your opinion changes. "itslikemicrosoftforcats" would probably get shutdown very quickly for the same reason - once you establish trademark for a brand name and make it well-known, other people trying to use that brand (which you spent a lot of time and money to build) for their own purposes are in the wrong. The exception would be if you can show the letter sequence really is coincidental, but the case we're discussing is a blatant attempt to cash in on Airbnb's brand.
