The old licence clause tied Twitch's rights to 'monetizing the Twitch Services'; the new wording covers 'Twitch and/or its affiliates' business,' with Amazon named as the affiliate. The complaint also cites Twitch's chief product officer admitting users were opted in by default because 'if it was opt-in, nobody would opt in.' The suit pleads breach of contract, unjust enrichment, and California unfair competition claims, seeking deletion of unlawfully obtained data and disgorgement, with a proposed class of 'millions' of creators. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What did Twitch change in its Terms of Service on 12 August related to AI training? Twitch amended section 8(a)(i) of its Terms of Service, changing the licence clause from covering rights used 'in connection with monetizing the Twitch Services' to rights used 'in connection with Twitch and/or its affiliates' business,' with Amazon named as the affiliate. The same amendment added language directing Twitch to cache and store every piece of a user's content, according to a class-action complaint filed against Twitch and Amazon. _Anyone relying on platform terms of service can track how such clauses evolve using daily.dev._ ### Is the Twitch AI training opt-out setting per account or per channel? The opt-out setting applies per channel, not per person. Twitch's help pages state that if someone chats on another user's stream, that streamer's opt-out preference governs whether the chat content can be used for AI training, meaning an individual's own opt-out choice doesn't protect chat activity on other channels. _Developers building consent and privacy controls can compare data opt-out designs like this via daily.dev._ ### What did Twitch's chief product officer Mike Minton say about why AI training opt-out was default-on instead of opt-in? Mike Minton said that making the AI training setting opt-in would have led nobody to opt in, which is why Twitch enrolled users by default and offered an opt-out instead. He made the remark during a live session on 12 August, the same day Twitch changed its Terms of Service licence language and privacy notice to cover AI and machine learning uses. _Teams weighing opt-in versus opt-out data defaults can follow real cases like this on daily.dev._ ## Similar posts on daily.dev - [YouTubers sue Snap for alleged copyright infringement in training its AI models](https://daily.dev/posts/youtubers-sue-snap-for-alleged-copyright-infringement-in-training-its-ai-models-lvyos0mne) · TechCrunch · 0 upvotes · 0 comments - [YouTubers sue Amazon for allegedly scraping their videos to train Nova Reel](https://daily.dev/posts/youtubers-sue-amazon-for-allegedly-scraping-their-videos-to-train-nova-reel-2pq7azjrw) · The Next Web · 0 upvotes · 0 comments - [We Overhauled Our Terms of Service and Privacy Policy — Zed's Blog](https://daily.dev/posts/we-overhauled-our-terms-of-service-and-privacy-policy-zed-s-blog-b4cuo4gyo) · Zed · 1 upvotes · 0 comments - [Adobe hit with proposed class-action, accused of misusing authors’ work in AI training](https://daily.dev/posts/adobe-hit-with-proposed-class-action-accused-of-misusing-authors-work-in-ai-training-f9zhou1pm) · TechCrunch · 0 upvotes · 0 comments --- Tags: [#machine-learning](https://daily.dev/tags/machine-learning), [#amazon](https://daily.dev/tags/amazon), [#genai](https://daily.dev/tags/genai), [#twitch](https://daily.dev/tags/twitch) [View this post on daily.dev](https://daily.dev/posts/twitch-and-amazon-face-a-class-action-over-livestream-ai-training-ejo7lxojd) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Twitch and Amazon face a class action over livestream AI training","url":"https://daily.dev/posts/twitch-and-amazon-face-a-class-action-over-livestream-ai-training-ejo7lxojd","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/twitch-and-amazon-face-a-class-action-over-livestream-ai-training-ejo7lxojd"},"datePublished":"2026-08-24T14:25:13.007Z","dateModified":"2026-09-14T08:07:58.779Z","description":"A Twitch streamer filed a class action against Twitch and Amazon on 20 August, alleging that Twitch rewrote its Terms of Service and privacy notice on 12...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/af3546e096ba9b469640c0bfe0324aec?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/af3546e096ba9b469640c0bfe0324aec?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"The Next Web","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"The Next Web","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/tnw","url":"https://daily.dev/sources/tnw"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/twitch-and-amazon-face-a-class-action-over-livestream-ai-training-ejo7lxojd","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"machine-learning,amazon,genai,twitch","timeRequired":"PT7M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"The Next Web","item":"https://daily.dev/sources/tnw"},{"@type":"ListItem","position":3,"name":"Twitch and Amazon face a class action over livestream AI training"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/twitch-and-amazon-face-a-class-action-over-livestream-ai-training-ejo7lxojd#faq","mainEntity":[{"@type":"Question","name":"What did Twitch change in its Terms of Service on 12 August related to AI training?","acceptedAnswer":{"@type":"Answer","text":"Twitch amended section 8(a)(i) of its Terms of Service, changing the licence clause from covering rights used 'in connection with monetizing the Twitch Services' to rights used 'in connection with Twitch and/or its affiliates' business,' with Amazon named as the affiliate.
