My wife and I own three chain restaurants. I am not going to say what the restaurant is but there are over 1400 locations nationwide with another 220 units planed for 2013.
We had our national convention in October in Las Vegas. The franchisor franchisee relationship is very strong. At our convention there is a meeting for owners where we can complain to our franchisor about anything we chose, as long as it is constructive.
This year the number 1 complaint was Yelp and their tactics, some of which you stated above.
Several weeks later all owners received a email from the company president telling owners NOT to deal with Yelp, or ever pay them a dime.
Yelp is not going away anytime soon, but time will tell if they can become a profitable business.
