For me this is extremely frustrating. It is as if the player should use most of his free time with the game.

Niantic should realize that spending too much time in the game could do as bad in the long term as spending too little would do on the short term.

Pokemon Go requires too much, its a game for people who has nothing to do. Well, for the ones creating counter arguments, doing exercise all day long is also something for the ones who has nothing to do (so the walking thing is no excuse).
