In a very similar situation to OP, this move totally broke a volunteer-run platform that allows (allowed...) users to report issues with bicycle lanes, missing racks, dangerous spots for cyclists etc...

The app is very basic, but has amazingly little barriers to entry. Notably you don't need an account to just report things, what I'd call an "open door" app. Sadly, without gps exif, this is much higher friction now. Pretty pissed at this. It's not hard to design a clean flow that permits to inform the user specifically of location sharing in the picker.
