Following a concern expressed by a user at How to share a Google Sheets demo spreadsheet.
The problem with sharing it editable is that anyone can trash the sheet. Surely it's better just to share it read-only and let people make their own copies to work on.
The above genuine concern extends to any file stored in my Google Drive.
So I decided instead of replying using a comment, to turn it to a full question.
Can a publicly shared file stored in my Google Drive be deleted by someone having "Anyone with the link" editor rights?
