Post I saw from GP didn't give any reasoning whatsoever. Merely said, "I loathe Airbnb." Perhaps it was edited after I saw it and before you did?
People criticize Airbnb here all the time. Anyone can eyeball https://hn.algolia.com/?query=airbnb&sort=byDate&dateRange=a... to see that it's not an issue.
In case anyone cares, liking has nothing to do with this. I dislike many perfectly fine-for-HN comments, and like many of the ones we moderate. For example, I like internet rants, at least the well-crafted ones. They lessen the monotony of reading crud all day. But it doesn't mean we won't ban you for it.
Despite the complete conviction of every troll in the neighborhood, the rules here are relatively objective.
