People who are mad that things got turned upside down in the ST didn’t truly want the ST to begin with (and that’s okay).
That’s not true. Just because someone didn’t want things reset to our heroes being a small band of rebels against a huge empire again doesn’t at all mean that they didn’t want more stories. It’s not as if there’s no other story to tell.
I’m not saying the ST had to be this exact story, but, barring something stupid as shit like an extragalactic threat, it was always going to be some sort of version of this.
For the ST to have stakes and not be entirely worthless and without meaning, the victory at the end of ROTJ had to be challenged to some extent, and the characters had to be something other than the boring, irreproachable and unharmable “heroes” we got in the EU.
