Huh?Huh?Posted Nov 30, 2007 16:15 UTC (Fri) by thumperward (guest, #34368)In reply to: This is a mistake, but he also provided a license, so it doesn't really matter by shieldsd Parent article: qmail released into the public domain
How is it "always best to provide a license"? I've heard the argument that a contrivance like the three-clause BSD ensures that the code is available even in states which do not recognise public domain, but I've never heard of anyone who experienced this difficulty. SQLite is also PD and has considerable uptake in large free software projects, commercial endeavours and in US government software. It doesn't appears to have been hindered by being PD. Do you have anything to back up your claim that it would have been "simpler", and that it would have "avoided needless confusion", by picking a contrived set of terms instead of a perfectly valid copyright status enshrined in law? Furthermore, BSD explicitly ties a work to an author. Perhaps this was the precise reason for choosing not to hold copyright over the work in this case. - Chris

Why a license is better than Public Domain Posted Nov 30, 2007 18:29 UTC (Fri) by jreiser (subscriber, #11027) [Link] How is it "always best to provide a license"?It is better for those who use the code, because a license identifies someone who claims to have authority to grant the license. One of the problems with Public Domain is that there is no identified authority. Anyone can claim that something called "public domain" instead is really theirs (was stolen from them.) A license provides users with a defense, and somebody to sue for not having legitimate authority to grant the license. Public domain opens users to attack from all quarters, and requires users to mount their own defense. Suppose that [a court decides that] the code really does belong to somebody else. Then a user who claims "public domain" is liable for intent to steal the code, while a bona fide licensee is not [excludes collusion between licensee and licensor to steal the code by creating a bogus license, etc.] In either case the user might be forced to discontinue using the code, but having a [supposedly valid] license tends to limit other losses.
There are reasons, this isn't particularly compelling Posted Nov 30, 2007 20:37 UTC (Fri) by kmself (subscriber, #11565) [Link] Proof and/or demonstration of authorship is one of the key parts of virtually any copyright dispute. In most cases it's sufficiently trivially accomplished that it's not given much thought. There are significant legal sanctions against false claims of authorship, and for a work as well documented and publicly distributed as qmail, chances of success would be low (though cooperation of djb in any defense would help). And having a license over a codebase doesn't necessarially free you from conflicting claims of ownership. Hell, it's even possible to imagine a world in which some two-bit thuggish company tried to claim a copyright interest in the Linux kernel. The better reasons for license, of some sort, are:
The cover of an approved license also greatly relieves the burden on those who would like to engage in further distribution, modification, and use of the work. For many FSF Free Software projects, having a clear check that works are granted under an approved and accepted license provides a very real and useful protection against real and imagined legal threats, from both outside and inside the organization. Mirror sites and CD/DVD services for CentOS, Debian, Fedora, and Gentoo come to mind. Likewise, odds of an effective attack against adopting a tool for use within an organization merely because it is licenced under GPL, BSD, or MIT license (and is hence "legally risky") wouldn't get far in any sane environment -- in almost any case such code is already in extant use. "Public domain" is a slightly harier threat at present.
Why a license is better than Public Domain Posted Nov 30, 2007 23:39 UTC (Fri) by ajross (subscriber, #4563) [Link] It is better for those who use the code, because a license identifies someone who claims to have authority to grant the license. One of the problems with Public Domain is that there is no identified authorityIn what was does Bernstein's announcement and the decade-long history of the product not constitute an identification of authority? This is very much a mountain out of a molehill. Sure, it's conceivable that you could get in trouble just grabbing source off the internet if you have to prove later on that it's legally useable. But it should be abundantly clear that that is not what is happening here. Really, are you honestly any more confused about where qmail comes from now than you were yesterday?
Why "oublic domain release" is a bad idea (Re: Huh?) Posted Dec 1, 2007 3:52 UTC (Sat) by PO8 (guest, #41661) [Link] First off, I Am Not A Lawyer, and nothing I say constitutes any sort of legal advice. That said, here's my lay opinion. 1) Lawyers I trust tell me that the whole concept of "releasing into the public domain" is of doubtful validity in US law. There are various ways spelled out in US law that a copyrighted work can enter the public domain. One of these is "abandonment" of the copyrighted material. But it is not clear to these attorneys that you can *explicitly* abandon a copyrighted work. 2) One of the rights protected by copyright is the right of attribution. If I were to take public domain code and claim to have written it, this would, I believe, be perfectly legal (as long as it wasn't part of some other actionable offense). If you are proud of anything in your code, you probably want to avoid that. 3) One of the things a (good) license tries to do is to control legal risks of release of material. Disclaimers of warranty and liability (for what they're worth) and legal terms of use can help to protect the author from expensive and potentially damaging litigation. 4) License notices and copyright notices are a way of protecting the user of a copyrighted work from a malicious author. Under current US and International law, published work defaults to "copyrighted" even in the absence of any copyright notice. The placement of copyright and license notices specify exactly which rights are granted by the author, and under what terms. Anyone who uses code from a large "public domain" release may run a substantial risk that the author may say "oh, but I didn't mean to release *that*" to a court. I wouldn't want to be defending myself from a copyright infringement charge over this. Conversely, if an author publishes copyrighted work related to her previous public domain work and inadvertently omits the copyright notice, it seems easy for someone unscrupulous to claim that it was part of the public domain release. Like I say, I'm not a lawyer. But for all of these reasons, I don't plan to release any more code for public use without licensing it somehow.
