Are people switching voluntarily or because it is the new default?
Interestingly, the computer keyboards are stuck with the old layouts. You can't buy a Russian keyboard with the right quotation marks. I am using a custom layout by Ilya Birman [1] that makes a nice remapping with «» available quickly.
Eg:
Féar - grass. Fear - man. Cás - case. Cas - turn. Lóndubh - (nonsense) black lunch. Londubh - blackbird.
Personally, I've always hated the ISO enter key and QWERTZ (although that's a bit of a tangent). I also think having a different keyboard for every European language is a losing strategy, especially when people might be required to type in two languages. If you know about it, for some languages the macOS approach works really well.
iOS is also passable; a long press brings up options (e.g. on s -> ß/ś/š). It's a bit more tedious.
As far as I can tell there's nothing like it in Windows - if you don't know how to input a special character, you have to open Character Map - which bugs me as someone living in continental Europe but using a US keyboard.
