Yep! RJ actually relocated to the Bay Area when writing TLJ so that he could be in constant contact with KK and the story group. I've spent nearly two years here laughing at the idea that RJ was given free reign to "go off the reservation." Just my (unpopular) opinion, but that's such nonsense.
Rian wouldn't be meeting with Dave Filoni, and asking him for guidance . . . and he wouldn't be constantly running things by the story group . . . and he wouldn't be having conversations with GL if he was just being allowed to do whatever the **** he wanted.
The reason RJ has repeatedly touted how much freedom he had is because he knows how to play the game. KK was (and is) having a perception problem that she doesn't give writers/directors any real creative freedom. Being a SW fan who desperately wants to make SW movies, RJ kept promoting how much freedom he had because that's the smart thing to do in order to keep working there.
Rian doesn't *need* the LFL gig; but he *wants* to make SW movies. The guy just started his own production company, has had most of his films met with enthusiastic reception from critics, and is even starting to get a little bit of Oscar buzz for Knives Out. He could easily say "F you" to SW and to all the crap he's gotten for it, but the dude loves this franchise. Playing ball with KK is his best bet to get to do more (and even that probably won't be enough).
