Twitch has confirmed it is using streamers' content to train Amazon's generative AI models, and has added a setting to turn that off. The setting is on by default, buried in privacy settings, and Twitch's own product boss said plainly that if it were opt-in, nobody would opt in.
Most businesses in Cave Creek are not livestreaming on Twitch, so on the face of it this is not your problem. But the pattern behind it very much is.
The part worth noticing is the default. Twitch did not ask. It switched everyone on and offered a way out for the people who happened to hear about it. That is now the standard approach across platforms where you post things: photos of your work, customer reviews, your write-ups, your videos, your social posts. If you have built up a body of content somewhere you do not own, assume it is being used to train something unless you have specifically said otherwise.
There is a second detail worth knowing. Even after opting out, Twitch keeps using AI for things like automatic captions and moderation, and you cannot turn those off. Platforms are drawing a line between AI that runs the service and AI that learns from your content to make new content. That distinction will show up in more and more terms of service, so it is worth understanding what you are actually being offered when a company says you can opt out.
And note this: chat messages you post on someone else's Twitch channel are still used for training if that person has not opted out. Your choices only cover your own patch. That is true more broadly. You control your settings, not the settings of the platforms where your content ends up quoted, embedded or reposted.
What to do
If you use Twitch, the toggle is at the bottom of Security and Privacy settings.
Otherwise, nothing urgent. But next time you speak to your developer, ask two things: what your own website tells AI crawlers about whether they can take your content, and whether the platforms holding your photos and writing have added an AI training setting you have not seen. The answer may be that you are happy to be included. Fine. Just make it a decision rather than a default.
