Once Airbnb became systemically harmful, regulation followed.
Nobody cares about small tech companies breaking the law for a few users.
Everyone cares about {insert bad outcome from mass regulatory avoidance}.
(Also, of the 3 airbnb founders, one has delusions of being the next Steve Jobs and turning it into an everything app (Chesky), another now works for DOGE (Gebbia), and the last is sucking up to Chinese government data requests (Blecharczyk)... so, yeah, not exactly the sort of folks that should be trusted with light regulation)
