Whether or not someone agrees that it's a screw up you are right, it will be fragmented. It's horrible (the way it sounds) from a game design point of view.
They can't seem to satisfy everyone, and it's the dissatisfied people who are the noisiest. I like this idea and think they're taking a big risk to attempt it, and I respect them for that.
They're losing subscriptions left and right. The community IS their income so they had to do something. In my opinion they chose the wrong direction to modernize their game.
