I don't think they can convince me they have actually reversed course on this. Its invisible so we wouldn't know if they kept on doing it secretly. It required building out technical capability which is unlikely to remain forever unused while conveniently available to them.

They relied on trust that they were providing the service they were being paid for. That trust was blown, and an "oops, lets undo that" does not regain trust. It would be prudent to assume the invisible guardraild are possibly in play for all future Clause use, Fable or otherwise.
