I bet most of those same people would lose their minds if their favourite restaurant tried to double prices overnight. "Yeah we sold a lot of burgers yesterday..."
If there was less egg available for a given day, McDonald's [^1] don't charge more for a McMuffin, they sell fewer McMuffins
I'd argue AirBnb's approach here is more like Uber's surge rates. Which are clearly more extreme than anything taxi cabs did (bar the occasional bad actor)
[^1]: mcdonalds is stretching the "restaurant" analogy here, but they have a higher consistent turnover so seem like a closer comparison
Restaurants are now double what they were, just a couple of years ago; even the cheaper ones.
The prices shot up, and have yet to back down.
