I mean with Lucas out of the picture, does anyone really care what the “true” canon is anymore?
In fairness, Pablo did say JJ contacted him regularly to check certain plot points. JJ is a shallow and poor writer, but he did at least seem to try. Even if he did muck up Rise in the end with his random rushed ideas, though part of that was the studio pressure.
Rian, who is a somewhat better writer, seemed to think his version of canon was BETTER than what those other nerds thought, so he just made up his own thing, regardless of whether it actually fit. See: Hyperspace ramming, which now changes the entire war now that one person can take out 30 ships. Why bother with weapons anymore? Just Holdo over and over until it works, it’s easier than actually shooting.
And then at the top, Bob Iger and Kathleen Kennedy don’t care either. Both have shown they are creatively bankrupt and don’t remotely care about the characterizations or plot. Bob even admitted his “1 movie a year” approach damaged the brand, and KK clearly had some sort of self-insert fantasy that Rian gave to her with Holdo.
