That's deliberately there to stop you from accidentally modifying a
backup file when you meant to be working with the regular file. If
you searched through the source you'd find this in files.el:

;; Make people do a little extra work (C-x C-q)
;; before altering a backup file.
(when (backup-file-name-p buffer-file-name)
(setq buffer-read-only t))
