Wouldn't the equivalent be incentivizing employees to rent out their own place on Airbnb? I'm sure that plenty of Uber and Lyft employees are customers without it being a Big Deal.
Yes, that'd be the equivalent to this specific situation. Airbnb incentivizes that as well. I don't remember the exact details, but in an interview with one of the founders, he said they have a program for employees who host Airbnb guests.
