Philly makes philly cheesestakes. If people don't like then they will find them awful. It's a bit silly to complain that they use cheese wiz, since that's pretty much the definition of what makes a philly cheese steak a philly cheesesteak now (Cheese Wiz was not yet available when the sandwich was invented,) and the two best known places sell eight to ten times as many sandwiches with Cheese Wiz than they do American or Provlone, and Pats maintains a warehouse of 15,000 #10 cans of the stuff.
