I'd also agree that Uber/AirBnB do not really fit well in that comment. These are companies that mostly just serve as middlemen. They could theoretically be entirely decentralized enabling people to genuinely connect directly with other people to offer a service. There are even technological solutions towards avoiding bad actors and abuse. For instance mutual facial recognition to ensure people are who they say they are - when you get in a ride, you and the driver both snap a pic of each other, it's verified on both ends, and off you both go. And all metainformation could be publicly stored in a trustless append-only decentralized ledger.
They're just the early middlemen of budding industries that, in an optimistic future, will not even need middlemen.
