Hi @mootari – sorry for the slow response on this. The site’s current treatment of forks of link-shared notebooks is actually intentional behavior. When a user chooses to enable link-sharing for their notebook, it’s an indication that they don’t want it to be discoverable on the site and listed in places like their public profile or the explore page. To avoid exposing the notebook somewhere that the owner does not desire or expect, we extend this logic to public forks of the notebook and do not surface information about a private or link-shared parent notebook when a public fork is being viewed.
If the parent notebook is published, however, attribution on the forked notebooks will become publicly visible (not only for future forks but retroactively for all forks of the notebook). But if you don’t wish to publish the notebook, some other options would be to (1) add a copyright / license to the parent notebook prior to enabling link-sharing, (2) comment on the fork(s) requesting attribution, or (3) add attribution to the notebook content itself prior to enabling link-sharing. Hope this additional context helps.
