See https://www.tuhs.org/Archive/Distributions/Research/Dan_Cross_v8/statement_… which reads: Statement Regarding Research Unix Editions 8, 9, and 10 Alcatel-Lucent USA Inc. (“ALU-USA”), on behalf of itself and Nokia Bell Laboratories agrees, to the extent of its ability to do so, that it will not assert its copyright rights with respect to any non-commercial copying, distribution, performance, display or creation of derivative works of Research Unix® Editions 8, 9, and 10. The foregoing does not (i) transfer ownership of, or relinquish any, intellectual property rights (including patent rights) of Nokia Corporation, ALU-USA or any of their affiliates, (ii) grant a license to any patent, patent application, or trademark of Nokia Corporation, ALU-USA. or any of their affiliates, (iii) grant any third-party rights or licenses, or (iv) grant any rights for commercial purposes. Neither ALU-USA. nor Nokia Bell Laboratories will furnish or provided support for Research Unix Editions 8, 9, and 10, and make no warranties or representations hereunder, including but not limited to any warranty or representation that Research Unix Editions 8, 9, and 10 does not infringe any third party intellectual property rights or that Research Unix Editions 8, 9, and 10 is fit for any particular purpose. So not exactly the sweeping "We own this and you can do whatever w/o restriction" license one would like, but still much better than "in the wild and unchallenged"... Caldera did those about 10 years prior to V8-V10 being available. https://9p.io/plan9/about.html has details on plan9, but the latest versions are available under the MIT license. Warner

(For those on the TUHS list wondering about context, here it is. I "ported" the document in the Subject line to groff and re-typeset it, discovering some spacing nits in groff and, apparently, a bug in AT&T troff as well--one equation[1] in the sources not appearing in published versions has risen from the grave when rendered with groff. https://lists.gnu.org/archive/html/groff/2022-07/msg00002.html ) [Ingo Schwarze wrote:] At 2022-07-02T12:51:16-0400, Clem Cole wrote: I believe even early releases of Plan 9 and Infero are both now fully liberated, though the former[2] took much longer than the latter[3].
