Disney is going to do whatever makes them the most money. I don't think the passionate Star Wars fans like us are really the majority anymore. Much easier to woo and make new generations of fans. Maybe a boycott would work, but for every disappointed fan, there is one that loves it and plenty more to woo.
I think the real nail in the coffin for Star Wars isn't going to come from passionate fans - it's going to come from over-saturation and the general populace getting tired of it.
The same thing is already sort of happening to Marvel, but I think they generally manage to stay afloat by jumping to different genres. Star Wars, I feel doesn't have that same flexibility. You can't change it too much because at some point it ceases to be Star Wars and then starts being one of those really generic, near-future, dystopian YA novel movie adaptations.
