Few frown upon but they still play. Game too good, addiction too strong, reasoning gets tossed out of the window... rest aren't smart enough to see it is just carrot and stick instead of well made game.
From what I've read, companies like coffee shops, fast food restaurants are already using Pokemon GO to 'lure' customers. They buy lure modules meant for regular gamers but I hear that Niantic is working on premium modules, for commercial use. As I said, this is just beginning. In next two years there will be flood of similar games, every major franchise will have one. Instead of running around, people will go to commercial venues to 'play' the game.
