Britannica and Merriam-Webster Sue OpenAI Over Copyright Violations

Executive Signal Summary

Encyclopedia Britannica and Merriam‑Webster have filed a lawsuit against OpenAI alleging large‑scale copyright infringement, claiming nearly 100,000 online articles owned by Britannica were scraped and used to train OpenAI’s large language models without permission. The complaint accuses OpenAI of producing outputs that reproduce full or partial verbatim content and of using Britannica’s articles in ChatGPT’s retrieval‑augmented generation (RAG) workflows. The suit also alleges Lanham Act violations for false attribution when the model hallucinates. The filing joins multiple publisher lawsuits against OpenAI; a similar Britannica suit against Perplexity is pending. The legal landscape over using copyrighted material as LLM training data remains unsettled.

400 US Local Newspapers Sue OpenAI and Microsoft

Nearly 50 U.S. publishers that operate about 400 local newspapers have filed a joint lawsuit against OpenAI and Microsoft, alleging the companies systematically used publishers' content without permission to train AI models. The complaint, published via Bloomberg Law and reported by outlets including FAZ, claims the defendants scraped publisher websites — including paywalled content — removed author attribution, and enabled their models to reproduce articles verbatim. Plaintiffs seek damages and an end to the alleged practices, warning of a potential 'death blow' to local journalism. OpenAI denies the allegations, saying its models are trained on publicly available data and invoking the U.S. fair-use doctrine; OpenAI founder Sam Altman has previously acknowledged that training cannot occur without copyrighted material. The dispute is among roughly 120 pending copyright suits against AI operators in U.S. courts.

Seattle Times and Newsday sue OpenAI and Microsoft over AI training

The Seattle Times and Newsday have filed a lawsuit against OpenAI and Microsoft, alleging that the companies used their copyrighted journalistic content without authorization to train AI models. The publishers claim that the companies systematically scraped articles, bypassing paywalls, to feed their systems, thereby diverting traffic and digital ad revenue. The lawsuit also raises concerns about AI-generated 'hallucinations' falsely attributed to the newspapers and the removal of copyright management information. It describes generative AI as 'a snake eating its own tail' that could destroy journalism. This case follows a similar lawsuit by The New York Times in 2023 and adds to the growing legal battles between media companies and AI firms. Notably, Microsoft and OpenAI have previously funded journalism projects at The Seattle Times. Microsoft expressed surprise but a willingness to resolve the dispute. The lawsuit was filed on September 7, 2026.

Unlocking Claude's Full Value: Plans, Workflows, and Setup

This article analyzes the economics of Anthropic's Claude subscription plans, comparing them to OpenAI's offerings. SemiAnalysis found a $200 Claude Max plan provides about $11,700 worth of Claude Opus 5.5 usage at API prices, versus roughly $2,100 for OpenAI's equivalent. Most subscribers use only a small fraction of their allowance, making the plans profitable for Anthropic. Recent product changes, including the merger of Cowork into Claude chat, new model versions (Opus 5.5, Sonnet 5.5, Haiku 5.5), and monthly API credits on Max and Team plans, make it easier to use the full allowance. The article provides a comprehensive guide with model routing tables, a map of the Claude stack, a 5-layer operating system, and 17 workflows to help users maximize their subscription value.
