OpenAI and Microsoft records describe chatbots replacing visits to the sources they draw on

OpenAI's ChatGPT chief wrote that its products "are largely substitutive, period," in internal documents made public September 17 in the Times lawsuit. That helps publishers argue over AI search, where Fast Company says the money is, but the labs still set the price.

Every AI-crawler opt-out in a 185-site European robots.txt census blocks the whole site

Pennyforge's 1 October scan of 185 European sites found 35 AI-crawler opt-outs in robots.txt, every one sitewide. That gives the EU consultation on opt-out signals, closing 3 November, a baseline where three in four sites show crawlers no AI rule at all.

One curl from a home laptop in Japan added three requests to a ClaudeBot total

One site logged 13,491 crawler requests in thirty days and could prove the origin of roughly 2,200 of them, because half the traffic came from vendors that publish no addresses to check against.
