Precisely because there *is* force involved: copyright law is enforced, ultimately, by police with threats to put you in a box forcibly. But that force, it must be recognised, comes from the force of law. The GPL, and all free software licenses, do *not* force anyone to do anything; exactly the opposite is the case. Free software licenses grant specific exceptions to the enforcement of copyright law. They grant freedom to do things that would otherwise be prevented by force or the threat of force. This is obvious when you consider what would be the case in the absence of any free software license: everything that was prohibited is still prohibited in the absence of the license, and indeed some more things are now prohibited as well. Conversely, in the absence of any copyright law (not that I advocate that situation), copyright licenses would have no force in or behind them. So I object to muddying the issue by misrepresenting the source of that force. Whatever force there is in copyright comes from law, not any free software license. -- \ “Let others praise ancient times; I am glad I was born in | `\ these.” —Ovid (43 BCE–18 CE) | _o__) | Ben Finney -- http://mail.python.org/mailman/listinfo/python-list
