I am disgusted but not surprised. When I was commuting back and forth between SFO and PDX I had apartments in both cities. I was able to dramatically offset my costs by Airbnb'ing the apartment I wasn't in at any given time... this helped me launch my business and I'm so thankful for that! The first time this worked out it was an obvious win/win for me and the renter. Right after being excited my next thought was... "wow this really let's the little guy do a little better"... I'm sure this won't last...
