People don't like TLJ because they're gatekeepers and thus whiny man-babies: such is my understanding of the narrative being promulgated by social media.
As I mentioned above, it's a tried and tested way of dissociating the product from objective criticism by making all criticism seemingly irrational in origin, and possibly even painting the studio as brave for standing up to those against a progressive social ideology.
On another level, it could also be argued to stigmatise sci-fi fans by presenting them as opposed to the hopes and dreams of little girls who look up to Leia or Ray - again, a tried and tested narrative from the PR campaign for the Ghostbusters remake - despite sci-fi fans (in their own faltering, clumsy ways) having pulled for diversity since the 1960s. With the TLJ hubbub, it seems like there's a conscious effort to paint Star Wars/sci-fi fans as the enemy of progress, while unquestioning and compliant consumers are the only ones who really "get it."
I presumed that point of the 'Anthology' films was so they could be more experimental with style and genre within the SW universe, while keeping the mainline 'saga' films more traditional in feel. From the look of things they are back-pedalling in this a bit.
Now this is just me, but I assumed the anthology films were to hoover up the "Star Wars knock off" cash. Back when Star Wars first came out, there were tons of knock-offs, usually missing the tone or point of SW, but still making plenty of money and some still being remembered to this day - Battle Beyond the Stars, Star Crash, etc. I think Disney just want to have their cake and eat it.
