You'd think that businesses that are part of something dubbed the "sharing economy" would play nice. Well, think again.

Take it from the CEO of one of the world's largest hotel companies: If you want to sample an authentic neighborhood when traveling, go with an airbnb rental, not a hotel.

The motto for mock toilet-sharing app AirWC is "'Cause taking a dump doesn't mean you have to be in one."

It sure seems like a stretch to say that selling a public parking space or renting out multiple apartments to tourists constitutes "sharing."

As Uber, Lyft, and airbnb expand around the globe, even smaller cities like Grand Rapids are feeling forced to regulate sharing economy businesses.
