Apple have been forcing user experience changes for years now. Removing physical buttons, removing TouchID, adding increasingly conflicting and difficult to discover gestures, acting like the iPad Pro keyboard should be a touch-type style keyboard instead of a two-thumb hunt & peck...Why? I pretty much always hold my iPad in portrait ... just feels more natural in the hand. If I'm watching something, I'll turn it, but the form follows the function, as it should be. One of the best parts of the iPad was always the ambiquitous nature with which you could use it. Trying to "force"' a user experience is the very definition of bad design.
...then there’s the obsession with thinness, and the ugliness of “flat” design (I am so effing sick of hearing the abused and meaningless usage of “clean” when stupidly simplistic UI designs are promoted).
Don’t forget all the arbitrary changes just to push a new version of the OS to push a new device sale every year...
