I don't understand why the editors allowed the engineers' names to be made public. What did they hope to gain by doing this other than making them magnets for harassment and possibly threats?
The identities of the engineers are now unambigiously in the public interest as they now have an impact on the government. These aren't scrappy hackers trolling on internet forums.
They're public servants. Most public servants have their name, position, level, salary, etc listed in public datasets. There is no "doxxing" of public servants. This isn't a usenet.
In normal circumstances, e.g. as contractors I would agree. However, they are not, as far as I can tell they are operating as federal employees. No federal employee name is private.
I do see this (article) as mostly retaliation though. Maybe deserved or not. Hard to tell at this point. But these people are public employees nevertheless, they never had the option for anonymity.
