Perplexity's definition of copyright gets it sued by the dictionary

Merriam-Webster and its parent company Encyclopedia Britannica are the latest to take on AI in court.

They are also alleging copyright infringement for instances where Perplexity's AI creates false or inaccurate hallucinations that it then wrongly attributes to Britannica or Merriam-Webster. The complaint, filed in New York federal court, is seeking unspecified monetary damages and an order that blocks Perplexity from misusing their content. "To build its substitute product, Perplexity engages in massive copying of Plaintiffs' and other web publishers’ protected content without authorization or remuneration."
