Pick up nearly any published book. Turn to the ~3rd page. There will be either a whole page, or sometimes the second half of a page, dedicated to a copyright notice. Very nearly every published book I've ever seen has that identical page. This isn't a recent thing. I grabbed my copy of Diaspora by Greg Egan and opposite the table of contents is a page that starts like this:

Copyright (C) 1998, 2015 by Greg Egan

First Night Shade Books edition 2015

All rights reserved. No part of this book may be reproduced in any manner without the express written consent of the publisher, blah blah (it felt very ironic to transcribe that bit in particular to make this point)

Standard copyright boilerplate. Not terms of service distinct from copyright, which is the subject of this thread.

This is what I meant.
