That's 3 selection biases here: Visibility on HN(selects for an "interesting" story, not truth), disgruntled employees, comments will want to rant about AirBNB. It's almost certainly a mistake to judge them negatively based on this story.
> In 2015, Glassdoor ranked the company as the #1 place to work, in 2017 that ranking dropped to 35th, and many employees are speaking out.
35th "best place to work" and "people are treated like cattle"? Somebody's giving you misleading statistics: Either it's Glassdoor.com, or the managing editor of "broke-ass stuart".
I don't think there's a single company above 10,000 employees that you couldn't force a similar framing on.
