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.

The online discussion forum says Anthropic continued to access its site more than 100,000 times after saying it had stopped.
