I suspect Springer would be interested in trying to prevent further occurrences. Retracting an entire book might be a bit difficult, but an editor might wish to leave out the chapter in any later editions and also make sure the culprit is not invited to be an author in future works.
I suspect that Gedela wishes to appear to be a scholarly leader churning out lots of articles. Thus the plagiarism. If I were a Springer editor working in this field, I would at least want to be alerted to this.
