A hill that I'll die on is that Apple's terminology is more correct than PC terminology for this.

Backspace makes sense if you see the computer as a fancy typewriter.

Delete makes sense if you consider the actions from first principles.

Consider the various forms of deletion (forward, backward, word, file deletion, etc.) Each of these just has a modifier key in Apple's way of thinking. (None, Fn, Option, Cmd) which makes complete sense when viewed against how consistent it is with the whole set of interface design guidelines for Apple software.

The only reason that this doesn't make sense is that it's incompatible with your world view brought from places with different standards. They will never "fix" this as there's just nothing to fix.
