No, it's because frost punk 2 sucked on every level. People are screaming for narrative driven story Rich games, and what you provided was a bare minimum politics simulator with a minor aspect of City build survival with very little story, and a extremely difficult game to actually balance
And all of this is disregarding the fact that frostpunk one was already fairly steep in price for what you got, and then frostpunk 2 released at and even higher price for even less game.
This is them seeing their failure that is frostpunk 2 and not being able to build on any of the constructive feedback that they've gotten from any of their bad reviews, and saying oh well we can't be the problem people must not like story anymore.
