↑ Placing documents into the public domain by Daniel J. Bernstein on cr.yp.to "Most rights can be voluntarily abandoned ("waived") by the owner of the rights. Legislators can go to extra effort to create rights that can't be abandoned, but usually they don't do this. In particular, you can voluntarily abandon your United States copyrights: "It is well settled that rights gained under the Copyright Act may be abandoned. But abandonment of a right must be manifested by some overt act indicating an intention to abandon that right. See Hampton v. Paramount Pictures Corp., 279 F.2d 100, 104 (9th Cir. 1960)."" (2004)
↑ Lawrence Rosen (ngày 8 tháng 3 năm 2012). “(License-review) (License-discuss) CC0 incompliant with OSD on patents, (was: MXM compared to CC0)”. opensource.org. Bản gốc lưu trữ ngày 12 tháng 3 năm 2016. Truy cập ngày 23 tháng 10 năm 2019. The case you referenced in your email, Hampton v. Paramount Pictures, 279 F.2d 100 (9th Cir. Cal. 1960), stands for the proposition that, at least in the Ninth Circuit, a person can indeed abandon his copyrights (counter to what I wrote in my article) -- but it takes the equivalent of a manifest license to do so.:-)[...] For the record, I have already voted +1 to approve the CC0 public domain dedication and fallback license as OSD compliant. I admit that I have argued for years against the "public domain" as an open-source license, but in retrospect, considering the minimal risk to developers and users relying on such software and the evident popularity of that "license", I changed my mind. One can't stand in the way of a fire hose of free public domain software, even if it doesn't come with a better FOSS license that I trust more.
