I would add that pushing users to behavior the company wants, but users mostly don't, as a very common reason. Sometimes more profitable features don't get the hoped for amount of traction, or the company wants to push users towards behavior that lets them collect more data or show more ads. I've seen even stupider reasons too, where a team is sad that some functionality isn't getting used much, so they push for a redesign to shove users into it. There are valid reasons to redesign an app but I would say that the majority of them are not done for the benefit of the users.
