Hmm. There was some kind of issue with that in the EU that led to the creation of a Creative Commons license, IIRC. Maybe nonstandardized handling of stuff not under copyright. I remember that in the US, putting something in the public domain wasn’t an issue, but in at least some of the EU, it was important to use Creative Commons instead.
I think that something not being under copyright isn’t analogous everywhere.
In 2009, Creative Commons released CC0, which was created for compatibility with jurisdictions where dedicating to public domain is problematic, such as continental Europe.[citation needed] This is achieved by a public-domain waiver statement and a fall-back all-permissive license, for cases where the waiver is not valid.
