IME they very much do care, they're simply not aware that a constantly changing user interface is not just something you have to deal with, like death or taxes. Every time I play tech support for friends and family it's the same story about how everything looks different yet again and how they can't find that thing that was right here just recently. (For myself I have cobbled together something that looks roughly like Windows 95 did decades ago, but doing that for others comes with its own problems, so not forcing that on anyone.)
