I think we're over-estimating how big and widespread this story is, because it's all over the HN front page. Sure, plenty of people are going to hear about it and it's gonna be damaging for airbnb. But a whole lot of people aren't going to hear about it because they don't read HN or the Financial Times.
It's bad for airbnb, but shouldn't be a killer. From my point of view, my only surprise is that it didn't happen sooner.
