I agree that the general direction of the most recent movies was awful and that it killed a lot of interest in the movies, but Disney has enough money to keep the universe alive until it finds its next successful franchise. Disney + plays a big role in maintaining a solid pipeline of content / storylines to build on.

Disney didn't just buy the characters we've seen in movies but bought the entire universe. At some point they'll find a storyline that's a hit. If I had to guess it will be mostly removed from the stories in the movies but exist somewhere in the Star Wars universe.
