There's an incentive for scholarly publishers and authors to have their works cited on Wikipedia, since there is a belief (supported by some research [0]) that citation on Wikipedia increases subsequent scholarly citations to those articles. Such a benefit could be used to increase a Journal Impact Factor & similar metrics [1,2] or the citations to one's own works, which is beneficial to academics competing for promotion, tenure, and research grants which are partially based on citation metrics.[3] I wouldn't be surprised if there was some indiscriminate citation on Wikipedia to bolster the metrics.
