That&#x27;s the aspect of copyright I&#x27;m willing to support, but it doesn&#x27;t require DRMs, just a working justice system.<p>Also, sadly, publishers have many different tricks to rob authors out of the money from book sales. Bigger ones probably don&#x27;t care, but there are a lot of smaller &quot;entrepreneurs&quot; willing to lie and cheat, so one has to be careful (as my physics professor learned in a painful way).
