As for AirBnB I think the Uber vs AirBnB comparison is a really fair one. AirBnB is a very similar example of a company doing serious disruption and facing pretty severe friction in the form of established lobbies and laws... but they've not been accused of threatening journalists, hoteliers, or anyone else who's challenged them. That's the distinction being made here.
There are lots of startups that appear to be really riding the line that I think Thiel is identifying here (AirBnB, Tesla, and 23andMe come to mind) by taking risks in the name of getting innovative services to customers, not in the name of providing air-cover for cashing in at the expense of their users.
