This is right on the money. Everyone wants to do new and interesting work on a product, which naturally means changing things even if it isn't really an improvement. No one is going to put "maintained system that wasn't broken" on their resume.

One thing that has likely exacerbated this issue in recent years is "data-driven" product design. While I'm fanatical about evidence-based decision making, so many of these products are designed around a vague concept of "engagement" which is all about getting users to interact with the app as much as possible. While this is the natural end state for ad-driven companies, I find it very frustrating that a subscription-based service like Spotify feels the need to take as much control away from the user as possible.
