Having worked in the mobile space for the last decade, it is my experience that these UI/X changes usually are a side effect of new management (after a purge) or from way on high (the c-suite). Neither one of these groups know much about UI/X but hold strong personal opinions which they automatically believe must hold true for all users. I am currently in a tug of war over such UI/X change for a feature in a banking application, making the case that we have plenty of older users who will have massive issues with the current redesign. My suggestions on performing user testing on the new design to validate them has not received much support over the last weeks. And so, I have started looking around for other opportunities on the market (this is also why places with bad UI/X continue doing so, they select for the people who are ok with making it).
