OpenAI, Google, Microsoft and Anthropic offer publishers single AI-scraping block

OpenAI, Google, Microsoft and Anthropic have pledged to give publishers one standard instruction to stop their content being scraped for AI training, replacing separate commands for every bot. Microsoft will implement it from February 1, 2027, Google sometime in 2027 and OpenAI in coming months, while Anthropic says it has started. The move follows lawsuits from news organisations.
