In 2008-2011 on HN if someone worked at facebook you knew because they mentioned it so often.
Now you never hear anyone saying they work for Facebook because of all the negative externalities that Facebook and Instagram have had on the world that no one wants to be associated with them.
AirBnB is now in a similar situation.
When tehy first came out you would get lots of positive feedback from people about their service.
now that they allow whole home rentals and people are getting squeezed for living space and rising rents partially due to AirBnb taking those rentals off the market people have a far different opinion of the company.
Couple that with hosts are squeezing people with 100's of dollars in cleaning and other fees that dwarf the nightly rental costs.
Its hard to think of another company outside of Facebook that has blown all their good will so quickly and so completely.
You never hear someone claim to work at AirBnB anymore due to what the company has done to help ruin housing and rental markets.
Charitably I guess you could say that every company falls victim to the saying "You Either Die A Hero Or Live Long Enough To See Yourself Become The Villain."
