I don't understand your not understanding. Just because the band changes doesn't mean that the fans have to follow along if they don't like what they've started to produce. Everyone has their likes/dislikes. If someone makes specific reasonings for their tastes not following the new direction doesn't mean they are wrong. You're no better for making your comment than someone stating theirs.

For example, how many people that like Ministry have ever heard their true first album and actually likes it?
