Its a fake quote by Satoshi Tajiri and is intended as a satirical forum and Reddit post poking fun at fan demands, rather than a real statement from the Pokémon creator or Game Freak.
"You all think you have great ideas for Pokemon games, but if I actually listened to all of you and we combined all of your ideas in a game, it would be an unplayable monstrosity. You want a game with all the regions, but only the first generation Pokemons, yet all the legendary ones and such silly things. Whenever I receive one of these rants, I go to the development floor and read it out loud to all the Game Freak employees in a mocking voice, and we all laugh at you."
-Satoshi Tajiri, Creator of Pokemon
