I doubt the claim, but the sentiment I think is valid. If you think about what data these entities are holding, it's not unique to a single database or entity.

I doubt the claim, but the sentiment I think is valid. If you think about what data these entities are holding, it's not unique to a single database or entity. Your name/address/phone/ssn/etc. Is likely stored in so many places that the probability it gets leaked from at least one eventually I'd say is very nearly, if not 100%.
