Wish they named them. Usually I don't recommend it. But the combination of:

A) in EU; GDPR will trump whatever BS they want to try B) no confirmation affected users were notified C) aggro threats D) nonsensical threats, sourced to Data Privacy Officer w/seemingly 0 scruples and little experience

Due to B), there's a strong responsibility rationale.

Due to rest, there's a strong name and shame rationale. Sort of equivalent to a bad Yelp review for a restaurant, but for SaaS.
