I bet one could also synthesize that with things like the trend towards darker and edgier antihero stories that hit its stride in the 90s and how much liberal storytelling has leaned on vapid aesthetic tropes to delineate villains and heroes.

The Empire is the US, and it acts like the US, and to drive home to American audiences that despite the Empire acting like the US they were the bad guys Star Wars steeps them in Fascist aesthetics. Then you get another generation of Americans raised on darker and edgier media where the heroes are also villainous, and lazy stories where instead of making the villains villainous they just toss some allusions to Fascist aesthetics on them and call it a day, and just outright Fascist media like CoD, so when they look at Star Wars they just see America doing normalized things and looking powerful doing it.

Like I think it's not exclusively a problem with Star Wars but rather an entire media environment that helps socialize people towards making fascist conclusions, caused by the collaboration of liberals and fascists in Hollywood, in the comics industry, and in the games industry, as well as liberal creations tending to be vapid and aesthetics based things that can never really criticize the status quo (to which the whole darker and edgier trend was also a reaction). There's also a point to be made about how much American counter-culture has been reactionary and libertine instead of liberationist, and as those reactionary and libertine elements got mainstreamed they pivoted towards fascism as they started to perceive the left as a threat to their treats.
