These were individuals who intended on staying pseudonymous, operated something that was legal-but-disagreeable-to-the-public, but yet fell victim to a hack that spilled their identity. And in spite of that, journalists felt it ethical to use illegally obtained data in part to "out" them. Nobody to my knowledge called out the problems with this - or that this same ethically fraught tactic may one day be used by organised harassers and right-wing outlets to deanonymise people seeking abortion or gender-affirming care.
Here in the US, the First Amendment makes any legal remedy to this hard to achieve. Yet still, we could be doing far better than to passively condone the use of illegally obtained data in investigative journalism to highlight unpopular, perhaps even vile, but legal activities.
