Amazon will train on Twitch streamers' content by default, unless they opt out

Amazon-owned Twitch announced it will, by default, use creators’ stream content to train generative AI models across Amazon unless creators opt out. The policy triggered strong backlash because streamers are opted in automatically, and Twitch executives defended the default as a way to avoid near-universal rejection if it were opt-in. The change raises concerns about consent, creator control, and whether past content may already have been used in model training. Twitch says users can disable the setting in channel privacy/security settings. The development is negative for sentiment around Amazon’s AI ambitions and may intensify scrutiny of how major platforms source training data from users’ content, especially from highly personal livestreams.
