TMTPOST -- Media tycoon Rupert Murdoch’s Dow Jones, the parent company of the Wall Street Journal, and the New York Post sued Perplexity on Monday, accusing the generative AI company of illegally using its content for training AI and diverting traffic to its own platforms. The News Corp-owned companies accused Perplexity of training the latter's so-called "answer machine" with copyrighted material, using scraped human-created news content to generate responses to users’ questions, allowing them to circumvent the news websites. “What Perplexity does not tout is that its core business model involves engaging in massive freeriding on Plaintiffs’ protected content to compete against Plaintiffs for the engagement of the same news-consuming audience, and in turn to deprive Plaintiffs of critical revenue sources,” the complaint alleges.
