Project manager driven decision-making. Everyone wants to make a name for themselves, so every update gets a big UI overhaul even when it doesn't need one. Features get taken away when they don't need to be. Workflows get redone when they don't have to be redone. Imagine if this were to happen for something as important as Bash, people would revolt and fork, but in the big tech world you are beholden to these corporate products.

It's not just apple, its everything in big tech. Venmo just released an update where they moved key workflows around for no reason at all, and now I don't have muscle memory for the app anymore, but I'm sure some project manager justified it with telemetry and got a huge bonus for rolling out an update and showing downloads grew by 1% (which they probably would have anyway).
