Amino analyzed health insurance claims from 188M Americans

What Amino has done can easily be done with anonymized data. They only need to know patient age, patient gender, physician, location of physician, what the physician billed for (I assume the ICD-9 codes). I doubt there's enough information there to identify individuals.

Personally, I think this is a step in the right direction. I can easily see this data set getting larger and adding in other useful scenarios that would make it more useful for patients like me.
