A better analogy here is probably “every time you use VS Code, the files you edit get sent to Microsoft”.

Some legitimate concerns:

• You have trade secrets. Previously; you can use services like Bedrock, etc, with signed contracts and significant reputations. Your contract is between AWS and you, and stays within your AWS security boundary.

• Security breaches. Remember when Anthropic accidentally published the source tree of Claude code? Or Meta’s recent AI recovery bot that didn’t check if the supplied recovery email was actually the email of the Instagram account? The best way to reduce your exposure is to minimise storage.

• Weaponised T&S. For example what if Anthropic decided to build a classifier for “usage in unsupported regions” that’s super overbearing (as we see with Fable) and vacuums up all context/input/output if there’s Mandarin? Contractually they could now retain it forever, not just 30 days, for ‘trust and safety purposes’ and perhaps have AI scan for any new or interesting ML techniques at scale, for Anthropic’s own use? They say just can’t train Claude models on the data.
