If I understand the situation correctly, it should probably be enough if this journalist would anonymize the names in the article, so it can no longer be traced back to any individual. After so many years, that does seem reasonable.
Also consider that journalists were never allowed to just publish anything. There always had to be a public interest for them to be allowed to publish certain details about peoples lives, so it only makes sense that they'd have to remove it as this public interest fades with time, yet the impact on peoples lives remains the same.
Just imagine having to apply for a job when the first thing that comes up when googling your name is a news story like that. On the other hand, who really cares about that story enough that it's worth possibly destroying someones life over it?

From the text > “My only duty is to write and verify information,” Mr. Biancardi said from the apartment where he and Ms. Lotti worked 12-hour days at side-by-side desks. “Everything else comes after.”
Interesting that the privacy of the subjects he writes about doesn't seem to be a part of his thought process at all. If his defense was "There's still (and always will be) a public interest in this case", then I might have agreed, but with that attitude, I won't even call this guy a journalist.
