they train on your requests by paraphrasing them (which means rewriting them but keeping all the saliency) and removing their association with you

i don't know why this is so controversial, their terms are written to perfectly fit this training regime

if you are using bedrock, until very recently, they didn't see your requests and could not paraphrase. but too many people were using bedrock for too much stuff they wanted to see. so that's why the terms for bedrock changed for fable 5. this was the core of the palantir / defense dept drama with anthropic.
