Simple &lsquo;public domain&rsquo; publication will not work, because some will try to abuse this for profit by depriving others of freedom; as long as we live in a world with a legal system where legal abstractions such as copyright are necessary, as responsible artists or scientists we will need the formal legal abstractions of copyleft that ensure our freedom and the freedom of others.
