I don't use or support services like AirBnB for this reason. If any of these "disruptive" services actually cared about their customers, they would gladly comply with government regulations that are meant to protect us.
AirBnB is great if you're white, able-bodied, and have no expectation of quality (or even an expectation of a safe, habitable environment), but just Google around for issues of racial discrimination with hosts and AirBnB's complete lack of support for disabled people.
These are all issues that have been through the legal system for close to 100 years, yet now we celebrate when we throw out our progressive ideals for something as petty as cash savings?
