Why was/is there a lot of talk of Pokémon Go declining in popularity, truth or haters?

[brainteeth]

On one hand I can appreciate an educated editorial about an app that has reached its peak , but in my humble opinion some of these posts are people almost wanting Pokémon Go to fail. I play the game and so do most all my children and I was wondering if anybody had some legitimate thoughts on why people have so many polarized opinionson Pokémon?
