Reddit started a legal fight against AI giant Anthropic over data scraping, highlighting issues of content ownership and copyright in the genAI era.

Reddit’s lawsuit, which was filed Wednesday, accuses the Amazon-backed AI company of breaching its user agreement. “As far back as December 2021…Anthropic was already—without authorization and in direct violation of Reddit’s User Agreement—training Claude on Reddit users” posts, the lawsuit claims.

Represented by John Quinn of Quinn Emanuel, Reddit claims the maker of Claude AI is in breach of contract by using its content for training.
