Instead of […] a license that requires derivatives and other uses of the licensed material to retain the same license[,] Wikidata utilizes a license that has no requirements. This might sound ideal for “freedom,” but in reality, Wikidata seems to appropriate that particular FOSS imaginary of sharing while instead delicensing information into data by assigning it a CC0 license—allowing companies to extract, commodify, and otherwise use these data in ways to create systems without requirements to honor the license or reference the works that were utilized.
