Deliberate sabotage by Disney.
I'm serious. Let me explain.
Disney wants to establish a new star wars fan base. One made up of an alliance of nu-millenials, asian market, SJW,s Tumbelrinas and whole lot of other minority crowds.
They purposely don't want any of the old fans dictating the franchise direction. Disney wants to be in charge of it and having the old fans have so much swaying power is problematic to them. Yes you read that correctly. Star wars fans have huge influence and money purchasing power on the franchise. They even made Lucas change direction after Episode 1. Disney are scared by these fans as potentially it puts star wars films at risk of underperforming. Think of marvel films and how they are safe money makers because of the braindead fan support. Old star wars hardcore fans can be autistic as fuck. They can ruin a franchise anytime and that causes disney anxiety.
They don't want old fans fucking up their investment by having the risk of a flop occurring in the next films or they being ridiculed because they have not been appeased/pandered too. Simply put the power dynamic is not to disney's liking. The old fans has too much power. On the other hand these new fans can be melded by disney to like whatever they churn out.
So they want the new old fans to be gone. To be outraged. To call this fan fiction. They want this. They want them to be gone and make the road clear for the new drone fans.
Fans that will never complain about direction. Fans who will take anything up the ass. Fans who will love it no matter how bad it is. Fans that you can sell and merchandise to. Basically think the Marvel film fans situation. Guaranteed money.
