The short of it is that Chomskyan hypothesis has a giant edifice built upon a single central idea. A fraca in popular science (i.e., outside academic journals) arises between Chomsky and Pinker over these ideas. Some unknown researcher announces that his obscure language brings the whole edifice crashing down. Add in a touch of Sapir-Whorf to make accusations of racism credible, and Chomsky's well-known fondness for dismissing critics rather than engaging them in scholarly debate.
Basically, there were two debates (did Pirahã have recursion in the sense that Everett meant? and what constitutes proof or disproof of universal grammar?) that went on simultaneously, while someone apparently took the opportunity to smear Everett with the Pirahã study ban.
