Earlier quoted context omitted.
But the article points out that Disney doing that is exactly why Star Wars performance has been lackluster. They're now taking a step back because apparently the public doesn't want a steady drip of Star Wars same-old-same-old
Star Wars performance “lackluster”? Have you seen the box office returns for them?
I think it's somewhat absurd too, but part of the point being made in the conversation around this article is that Disney isn't taking risks or making decisions based on creative output -- they're very, very aggressively following market trends. Their first Star Wars release was one of their highest grossing films in something like a decade, but one bad showing from Solo and suddenly Disney is cutting back on yearly releases.
They want movies that are safe and predictable. They want to know before they even start production not just that the film will break even, but that it will make a LOT of money. Clearly based on their own statements, they don't feel that confident about a yearly Star Wars release.
