How does the presence of that information in Wikidata help if the Google
user just gets the info in the Knowledge Graph without any indication that
it comes from Wikidata? Because CC0 specifically waives the right to
attribution that Wikipedia retains.[1][2] No re-user of Wikidata content is
required to say where the data came from, and they typically don't.
The problem is that there aren't really any alturnatives to CC0 that do any
better (since wikidata isn't really copyrightable in conventional terms).
Open Data Commons Open Database License would be closest but only applies
in the EU and leads to messy arguments over what counts as a substantial
part
