Where are you getting that “Mandate from Disney” noise from? That flat out doesn’t make any sense.
Also, they didn’t “can” George Lucas’ scripts because George never turned in scripts. He had notes that he didn’t want to hand over as part of the sale, but then he did anyway. And apparently they were really weird and Osmosis-Jones-y stories about the Midichlorians - and even that we only know because HE said so in an interview with James Cameron. There were never “scripts” of the sequel trilogy for Disney to “can”
These sound like YouTube talking points, which are very often designed to infuriate you so you’ll keep watching because that’s how their algorithm works. Factual accuracy is - if you’re LUCKY - a secondary concern.
