There is a very serious error pervading this discussion. Everyone is working on the presumption that Wikidata is importing pure facts. This is false. Wikidata often imports creative works of authorship.
I went to Wikidata and clicked random item, it took me a matter of seconds to find an example of Wikidata copying creative work licensed under CC-BY-SA, specifically from English Wikipedia. An item popped up for a geographical feature, listing coordinates. When I checked it on a map, the contributor selected an arbitrary and highly unusual coordinate to represent the geographical feature. In particular, the coordinates consisted of 16 digits. Approximately 6 digits of that information was factual (within the geographical feature), and approximately 10 of the 16 digits were a creative work of authorship of the contributor.
I could very easily make a series of edits, adding valid coordinates to articles, and embed a watermark in my creative selection of precise location. A bot would soon come by and import my work into Wikidata. I could then prove my creative authorship in court by explaining how to read the watermark. The watermark spread across those contributions could contain the hidden text "Copyright by [email protected] licensed under Creative_Commons_Attribution-ShareAlike_3.0_Unported_License https://creativecommons.org/licenses/by-sa/3.0/ ".
Furthermore many text fields contain creative work. (In case anyone has difficulty with the concept of authorship of a string of digits, or of watermarks.)
A more accurate question for the lawyers is this:
Can you comment on the practice of bulk extraction from Wikipedia articles, of factual information AS WELL AS individually-short works of creative authorship licensed under CC-BY-SA , and publishing it in Wikidata under a claim of CC-0?
In addition, I'd like to specifically ask:
Could the assertion of CC-0 constitute Slander_of_title?
Slander of title might be more serious than the direct concerns of license infringement.
