Spiceworks published an article that concludes "AI is quietly cannibalizing its own supply chain" of human curated information, including Wikipedia, used to train models. Spiceworks' interest? They are concerned that at some point, as AI search engines regurgitate more and more AI-derived information, and users shortcut the venues that would have resulted in corpora of interaction in the past, now users won't be able to do searches for technical help – hence the title "Is AI quietly killing the forums and wikis your IT team relies on?"

Separately, Adweek drives a similar point, in an interview of a Wikimedia Foundation executive. The Adweek article, "Inside Wikipedia's Plan to Survive the Answer Engine Apocalypse", says "ubiquity without attribution is an existential threat" to Wikipedia posed by AI driven search engine previews (like AI Overviews).

Ina Fried, writing in Axios, says Anthropic and OpenAI – with a combined valuation north of two trillion dollars – are not among firms with publicly acknowledged paid access to Wikimedia Foundation feed for AI model training data. Strongly hinting that they are either freeloading, or simply not discussing it if they are in fact paying. Non-human traffic, including the scrapers used by some to acquire AI training data, accounted for 65% of cache misses in 2025.^[a] A new analysis of 2026 data appearing in this month's Special report suggests that humans are consuming just 33–35 percent of pageviews; bots have taken over the rest. – B

On October 5, The Verge reported on unauthorized automated access to Wikimedia Foundation assets including

edits to Wikimedia wikis, "unsuccessful attempts" to "exploit" the Etherpad note-taking tool that the Wikimedia Foundation hosts, and heavy traffic that the foundation says "may" have contributed to a partial outage that happened in May…
— Jay Peters, The Verge, "Wikipedia operator says OpenAI's 'rogue' bots may be linked to a May outage", October 5, 2026

Ars Technica followed with their own story the next day, characterizing the access of Wikimedia Foundation assets, collectively with access to other sites, as "actions that would likely result in criminal charges being filed had human hackers taken them".

Other coverage included Reuters and The Telegraph.

In 2022 the Arizona Department of Corrections "shortly before" executing a prisoner sent "a directive from a superior to an underling saying, 'Look up in Wikipedia to see what the appropriate dose should be.'"

That's according to retired U.S. Magistrate Judge David Duncan who was quoted by NPR in an "exclusive interview". Two other sources, Mother Jones and Death Penalty Info have given similar reports. These execution(s) were supervised by Frank Strada, then Deputy Director of the Arizona Department of Corrections in 2022.

Last week as Commissioner of the Tennessee Department of Correction, Strada supervised the botched execution of Christa Pike, and then quickly stepped down from the position. According to Pike's attorney "Parts of the (execution) protocols for both states are written down. And you can see that some of the sections are word-for-word identical."

Duncan should know what he is talking about. He was hired by Arizona's governor in 2023 to review questions about Arizona's system of execution and had access to internal documents and interviewed about 50 corrections employees. He was fired by the governor just before his report was to be released for exceeding the instructions he was given.

The Wikipedia article most likely referred to in Duncan's quote still included drug doses until this Friday, October 9, as did a few other related articles. In fact two sets of doses were given in the most likely article, the first was for orally administered doses given for physician assisted suicide, the second for intravenously administered execution.

According to Wikipedia's Manual of Style/Medicine related articles

"Do not include dose, titration or pricing information except when they are extensively discussed by secondary sources ... Wikipedia is not an instruction manual or textbook and should not include instructions, advice (medical or otherwise) or 'how-to's.'"

Other than this disregard of the Manual of Style/Medicine, this reporter could find little or no evidence of rule-breaking by Wikipedia editors.
