How to remove a photo's " Where from" information?

As a followup to How to remove the photos' information " W… - Apple Community, the wildly misleading answer is as follows:

No, you can't delete the "Where from" using an EXIF editor.

It's not actually part of the picture itself, but instead an extended attribute named "com.apple.metadata:kMDItemWhereFroms" on the file in the filesystem. In other words, it only exists on your Mac's HFS+ filesystem.

If this is nonetheless embarrassing somehow, it can be removed anyway using Bash.

$ xattr -d com.apple.metadata:kMDItemWhereFroms /path/to/file

If you're not really a Unix person, it's not hard to do this. Open /Applications/Utilities/Terminal.app.

Type the first part of the command above and drag the file from its Finder window atop the Terminal window -- macOS will put the pathname there for you.

BTW, that dollar sign is the Bash prompt and should *not* be typed.
