Wikidata's data have a CC0 dedication, which means that any data set with conditions of rights different from the public domain can't be imported into the project. Although we can and should meet the requirement of referencing the sources, the statement that Wikidata's data have the CC0 dedication would no longer be true if we mass imported data from WordNets (except for those WordNets in the public domain, if any).
