Whatever the controversies surrounding services such as Uber and Airbnb — from the contractor vs. employee debate to municipal regulation — the “sharing economy” boom in users and outreach is staggering.

However, the report also raised the concerns those polled had about the services: inconsistent quality or service, and lack of trust between the consumer and provider.

Though PwC used the “sharing economy” label, the report noted the debate over terminology:
