It's because HN is fundamentally biased and always will be. The top 2 comments are not surprisingly pro airbnb:
a) People are still good fundamentally - because that's exactly what I'd want to hear if someone ransacked my place.
b) PR from a guy who works there.
I personally wouldn't want to stay in a stranger's house and I don't think I ever will - no matter how big airbnb becomes I believe there will always be a percentage of people who are uncomfortable with the airbnb business model.
Obviously a lot of people don't care and airbnb will go on to be successful I'm sure but it's a shame this community has such a hard time being honest with itself.
