This sets a dangerous precedent that journalistic pieces could be deemed reputable harm and therefore in any case illegal. Just imagine someone wrote an article about Hitler in his youth calling him out for racist behaviour and they would get a verdict against the journalist, notwithstanding the fact that there’s merit in the criticism.
Of course there is a difference when it comes to unwarranted slander without any evidentiary basis. That’s something more akin to Depp v Heard.
