This drives me absolutely nuts too. There is just too much pressure from various different job functions within companies to constantly change things even if it doesn't actually improve the customer's experience. People don't want to maintain old products, they want to work on something new. Compensation and promotions are dependent on shipping a fancy new product (looking at you Google). Management pressures people below them to change something even though they don't understand the customer's needs. I'm sure you could come up with a dozen more reasons. This has gotten so much worse now that everything is a subscription web service and you can't continue using the product unless you accept whatever crappy redesign they have pushed out this time that took away the feature you liked using or the workflow you are used to.
