I have been in a big company where a single incident of possible PII leakage happened. (turned out it was a non-issue but) It was the biggest fire I have ever seen, with everyone bringing out every apology, every on call engineer, every lawyer, every HR person and every training there was to make sure it never happened again. Dunno about all of them, but I can confirm that at least some of the big-tech companies treat PII as nuclear fuel that is never to be touched and placed behind the strongest locks the company has available.
