It more has to do with an ingrained perception of the original intent of the film, Weyseed. The films were not supposed to be connected the way they are now, and to someone who grew watching them under the perspective originally intended and presented, accepting subsequent ret-cons being forced into the original material in ways that clearly weren't intended is so distracting that it simply cannot be accepted. Like if Lucas made an Episode VII where it was revealed that all along Han was really Luke's brother and Boba Fett was real Emperor while Palpatine was the decoy. You'd be like "huh?"--but all the pieces would fit, right?
