I think either you've prompted Claude misleadingly, or it's interpreting the law unnecessarily prissily (which is a failure mode I've noticed LLMs falling into).
This clearly is disclosed, otherwise how did we get to know about it?
They do not disclose when the service is degraded, and the admission of that here seems like it would do a plaintiff's work for them.
What's not clearly disclosed is when you are being limited and what the bounds are. If you are developing ML kernels for a computational photography use case will the safe guards miss-fire and sabotage or slow down your efforts? What about distributed GPU interconnect work for a nation super computer lab used in weather simulation?
The reason they are doing this shadow ban style technique, is they don't want users to figure out how to jail break their way out. Or the explicit direct bad PR of when it miss-fires.
