A review bomb is when people start jumping down the game's throat with negative reviews for shit unrelated/peripheral to the game. If they're triggered by the actual core design choices of the game it isn't a review bomb.
These reviews are because the game is a money grubbing downgrade from the game people bought and had taken away from them, and this is the first opportunity they had to publish a review on a storefront. The motivation being the actual game means it can't be a review bomb.
