I didn't mean to make it seem like I'm calling you out specifically, just thought it worth clarifying that there's no a priori reason that PII should be included in a crash report. Sounds like we agree.
Pseudonymous information always has a high risk of being abused for fingerprinting and thus denonymising. I feel that there needs to be a trade-off though: on public datasets, people should be very careful with pseudonymous identifiers. On things like crash diagnostics that are never meant to be shared I feel they're perfectly fine. That's why I dislike a general discussion where all PII is bad and evil without context.
