Hi, While I was starting to prepare a non-maintainer upload to re-introduce the patch that removed --will-cite, I realized that the patch was already re-introduced in version 20210822+ds-2 (see https://salsa.debian.org/med-team/parallel/-/blob/master/debian/patches/remove-overreaching-citation-request.patch).
As the patch shows, the "please cite" wording is still mentioned in --help and in the manpage's AUTHOR section (without the 10000 EUR mention). Also, --help points to the Zenodo for GNU Parallel 20210822 ('Kabul'), while the manpage points to the USENIX ;login: article, but that inconsistency is also present in the original version. So, everything looks fine from my POV. Lucas
