In one of the few cases that you can genuinely blame RLM for something, Ruin actually did admit that they scared him. So what likely happened was he juked and moved around stuff to make it less of a copy of The Empire Strikes Back. I personally think most of this idea is just fucking cope, but I can buy the film being rewritten. Disney's been incompetent in that regard just for a long time.
Ruin is high off his own farts and after Looper went all-in on sucking Critic Dick.
Tracking a script is nigh impossible to draw conclusions from because sometimes a script writer will bring to the writer's meeting the biggest, runniest, post-3am-tacobell-run turd possible on purpose just to shake things up and try to generate new ideas. Script writers often don't even remember what they were thinking by the time an edit is done. So I beleive at some point there was a not wholly shit TLJ where Rey joins Kylo to lead the first order, Luke has a change of heart with Yoda's force goes and leaves exile to go "save rey", but I dunno how long any of those plot points stuck around.
Like I think Ruin made a totally boss opulent throne room for Canto, then when that subplot dropped, liked the aethetics and convinced himself it wouldn't be out of place on a star destroyer.
My head cannon is Ruin was given complete creative control by KKK provided he cram it with as much Girlbossing as possible, which he didn't have a problem with.
I think given that TFA was just a retread of ANH, Ruin intended to make his film start as a retread of WSB, but then SUBVERT EXPECTATIONS by Luke refusing to train Rey & in general being a bitter old cuck, and inserting his Clever Political commentary that the Clone Wars and the Galactic Civil War and this new conflict were all rooted in the MIC profiteering (muh afghanistan!) - which honestly I'm going to give him is a better explanation for how the First Order magically showed up with a massive fleet and the Deathstar For Modern Audiences than the... literal nothing JJ gave us.
I think Ruin was out to unmask JJ as a talentless hack, and I think Star Wars was just an unfortunate casualty in that crusade."You mystery box making nepobaby. This is how you cleverly take a nod from a movie and then put your touches on it" I would need very solid, good evidence to move from this position given the number JJ's mystery boxes Ruin joyously and purposefully smashed on screen to show empty they were.
Rey's parents nobodies. Phasma just getting the shaft treatment. Luke's ESB lightsaber utterly inconsequential.
Anyway, to bridge this into another line of thought brought up recently, you can see there is no grand vision for the ST other than Rey = #1 Best Of All Time and "break all dies to lucas including making the MF's radar square for no reason" and "sell as many tickets as possible while also virtue signalling how woke we are". The PT had flaws in execution but there was a grand stategy, a over arcing narrative, and when you aren't buttmad because you've been told to expect the greatest movie ever for 2 years, you can see it.
The ST was none of that, just a soulless attempt to bilk an audience of abused wives. Who are still lining up to watch the latest shit cartroon despite knowing it will be bad.
The only part of Disney still consistently making money is the cruise line division.
Point of order, Themeparks (which includes Cruiselines iirc) is still making money even after eating the retardation of the Star Wars theme hotel. But the YoY gains aren't going like disney wants and defered park maintenance is going to hurt them bad over the next few years.
The issue with the Parks division is Disney has basically maxed out foot traffic. They cannot bring in new visitors to keep pace with revenue increase demands by investors, so the only way they have to increase revenue is to expand parks (expensive and risky) or by extracting more cash from each visitor.
This what Galaxy Rimjob was supposed to explore. They wre looking to gauge viability and consumer appetite for even more expensive "bespoke" park experiences, by targeting a consumer base of proven zero standards pay piggies
