It is icky. However, Ocaml, which is in main, has a clause (3b) with a similar effect: https://metadata.ftp-master.debian.org/changelogs//main/o/ocaml/ocaml_4.01.0-5_copyright >> * The software and the end-user documentation included with the >> redistribution, if any, must include the following acknowledgment: >> "This product includes software produced by UChicago Argonne, LLC >> under Contract No. DE-AC02-06CH11357 with the Department of Energy." > > This is a burden on certain forms of work.
