Perplexity has raised a First Amendment defense in Reddit's DMCA suit against it and SerpApi, following the same move Anthropic made in the Gilbert copyright case on Aug. 20, per Chat GPT Is Eating the World. Elon Musk, Tesla, and Warner Bros. Discovery were the first to raise the defense in an AI-copyright dispute, in March 2026; the site's author expects the argument to become a standard part of AI companies' litigation playbook.

Why it matters: A third AI company invoking the First Amendment against copyright and scraping claims, after Musk/Tesla and Anthropic, suggests the defense is becoming a standard part of how AI companies answer these suits rather than a one-off argument.
