public domain 和 free software （自由软件）是两回事
下面是 Richard Stallman 在 Revolution OS 里面说到的东西
Free Software generally does have a copyright. It does have an owner. And it has a license. It is not public domain. If we put the software in the public domain,
somebody else would be able to make a little bit of changes and turn that into a proprietory software package, which means that the users would be running our software, but they wouldn't have freedom to cooperate and share. To prevent that, we use a technique called "Copyleft". The idea of Copyleft is that it's Copyright" flipped over. And what we do is, we say, this software is copyrighted
and we, the authors give you permission to redistribute copies, we give you ermission to change, we give you permission to add to it. But when you edistribute it, it has to be under these terms, no more and no less. So that whoever gets it from you also gets the freedom to cooperate with other people, if he wants to. And then, in this way everywhere the software goes, the freedom goes, too. And it becomes an inalienable right to cooperate with other people and form a community.
自由软件一般还是有版权的。它也有所有者。有许可协议。并受到版权保护。如果我们放弃软件的版权，有些人就会对它做一些小改动，然后把它变成专有软件包。这意味着，他们的用户运行我们的软件，却没有合作与共享的自由。为防止这种情况发生，我们采用了称之为“copyleft”的手段。
Copyleft就是“Copyright（版权所有）”的反动。我们所做的就是，我们声明，这些软件是受版权保护的，而我们，软件作者授与你复制分发的权力，我们给你修改的权力，我们给你增添的权力。但是当你重新发布的时候，你的软件也必须给出这些授权，不多也不少。所以无论谁从你这里获取软件，也同时得到了与他人合作的自由，如果他想那么做的话。如此一来，这个软件传播到哪里，自由也随之而来。它成为与他人合作和形成社团的不可剥夺的权利。

哦，这就看似更下流无耻了
用了public的东西，不但不还报给public,还要问public要钱 |
