No... Not to stay relevant, to keep milking SW fans for cent they've got!
That's how you keep milking a cash cow mate. Business school 101. That's probably the ONLY reason the bought the franchise from Lucas. They probably turned a profit after the first business quarter after the initial purchase.
You better pray that Disney don't turn their attention to LOTR and decide to purchase the rights. They'll destroy it!
And that other part is a funny bit, lol... But it's been used as a comedic device for ages!
Don't worry, we already got Amazon and Rings of Power for that.
