Not about a console, but sometimes manufacturers or developers change the UI of the system or valued apps.

Examples:

Sony removed Linux OtherOS from the Playstation 3 firmware because even though it didn't have a GPU driver, they were worried it could be leveraged to do whatever. There is no value in running Linux on a PS3 today, but there was once.

Apple notably between iOS 6 and 7 changed their design language from skeuomorphic to flat white "metro" style. If you don't like staring at a glaring white screen, too bad. But more importantly, when it comes to drivers, esp. graphics, they can introduce eyestrain if something isn't as good. Issues with sound, networking, etc. for all sorts of platforms. The Intel Management Engine which is inside your PC (AMD has a counterpart) is a another CPU and another OS that you're not allowed to shut off (or access). Sometimes firmware updates will come out preventing you from rolling back to a previous version that didn't have a bug with the hardware in this or that because of the precious Intel ME backdoor.
