Strategically, this is KK’s best shot to destroy the Filoni-verse before it’s born. The High Republic is trash and a commercial failure, but if she can drive the old fans away, Disney will have no choice but to embrace her vision with no real alternative. This is a political move, self-destructive in the long run by a petty tyrant who does not want to lose power.
For me, I won’t watch Mando until and unless KK is gone. I’ve made it very clear that for me to come back to SW, KK must be fired, the sequels decanonized and if it were legal, Rian Johnson burned at the stake. So keep up the pressure, this is a negotiation with an amoral psychopath holding a loved one. You need to have the ability to walk away or that loved one is already dead. You also need to be able to come back to the table.
