probably pay-wall protest. At the very least its a "try-me" position to see how companies who implement pay-walls respond to this obvious outcome.
However, correct me if I'm wrong, reprinting wholesale a journal's article is a copyright crime in the USA, is it not? Or I guess it constitutes fair use somehow?
As a submitter doing a workaround, I'd much rather find a legit link to a non-paywalled version of the article, instead of copying content.
