It says that the people who made TLJ had no idea what they were doing. If anything, they made the heroic rebel side look idiotic and thoughtless, constantly shooting themselves in the foot for no good reason. The entire movie (and the PLOT of said movie) is a good argument for why SJWs should never be put in charge of anything.
Rian Johnson and Kathleen Kennedy were trying to present themselves as more clever than they really were. They share that hubris with Bob, who believes that subverting an existing work makes the act intelligent. Bob's problem is that his knowledge of comparative mythology is incredibly feeble. From what I understand, he disdains popular archetypes and the hero's journey because he sees them as tired cliches without understanding why they have endured for centuries. Joseph Campbell--whose work inspired George Lucas when he was writing the the original
Star Wars--was himself inspired like Sigmund Freud and Carl Jung who sought to better understand the human condition.
Bob (incorrectly) assumes that he understands the human condition in its entirety because chose the "winning" ideology. He assumes that he knows how myth and archetypes work as such and can deconstruct/subvert them, but lacks the tools to reconstruct them. Neither Bob, nor his contemporaries can abide by the notion that they have anything to learn since they already "know" everything. They lack the curiosity and drive to examine the various pieces they dissect beyond of the woefully narrow lens of identity politics. Imagine that Bob is disassembling a car, the frame may be the same but all the pieces would be in the wrong places. Even the frame itself would be warped in some places because he attempted to force a piece into a place where it did not fit.
Given his skewed perceptions, it does not matter that the Resistance were so inept that a bunch of bumbling Empire cosplayers wiped them out in the span of two hours. What Bob really wants is to take something scared to a group he despises, smash its icons, and pervert it out of spite so he can lord his perceived intellectual "superiority" over them. He could not give less of a damn about Star Wars or Marvel. If I had to speculate, I would theorize that this attitude stems from his experience with
Super Mario World 2: Yoshi's Island. Bob spent the majority of his childhood in the eighties and thus took the unofficial backstory that Mario and Luigi were plumbers from Brooklyn as scripture.
Yoshi's Island sees release in 1995 and establishes that the Mario Bros. were--in fact--always denizens of the Mushroom Kingdom. Nintendo effectively took a sledgehammer to his beloved icon and committed the ultimate act of heresy.
(That would probably be one of the chief reasons why Bob hates the nineties outside of Sega, and later Sony, breaking Nintendo's hegemonic hold on the industry.)
Since Nintendo will not give Bob "his" Mario back, he will join with the SJWs in their hostile takeover of popular culture. His embrace of social justice is little more than a flimsy raison d'être to take from others what Nintendo took from him.
