Alt-Printscreen does work as the original keypress, but I only remember this shortcut after I have already hit Printscreen and see the window appear.
That said, one thing that does bug me is the Ubuntu terminal behavior change that no longer respects right clicks for paste, or ctrl+v for that matter.
I had to go digging to restore that and was causing some havoc with vim as instead of pasting when in Insert mode, it would toss me in some -- Insert (visual)-- mode
I wouldn't be so sure that Microsoft will give you an easy toggle in the new control panel for this behaviour.
Settings -> Accessibility -> Keyboard -> Use the PrtScr key to open Snipping Tool.
it's not related to edge/bing so it doesn't affect revenue
Good on Microsoft, I guess!
