Why do Pokemon fans complain but still buy the game?

I was talking about this with my friend and I was just saying how I thought it l thought it was weird that people will hate on the game and say they haven’t liked a game for x amount of years but than still buy every game, I just thought this doesn’t make sense because they’re a decent amount of people who complain and if they all decided “hey I’m not gonna buy this game because I don’t like it” than Pokemon would have to listen to their fans alot more since their numbers are dropping but even people complain but than still give the company their money then the company can continue to be lazy.
