De-anonymization has NOTHING to do with the current scenario. When legal contracts are in place, they dictate the rquirements & restriction on using the data. Today you can go and purchase de-identified but NOT de-anonymized data from US government as long as you sign and abide by contract to use it for purpose of aggregate statistical reporting and research. Regarding your second point, yes all these issues have been considered in depth by policymakers in US government and NHS. And current rules/contracts already incorporate legal protections to prevent misuse in form of both civil and criminal penalties. If DeepMind had done something truly unusual or nefarious they would have been already prosecuted. But having failed to find any evidence of explicit misuse the authors of the original paper have shifted the goalpost into territory of vague arguments.
