I'm not sure I agree that you have to give a chance to respond - I think context matters.

I think if you make an accusation or cover a specific incident, they should be able to give their context, not out of fairness but as this might give a more accurate view of the truth

In this case, they presented a specific series of events showing a pattern of behavior, and a timeline of communication they made with billet (including their public comments in the subject

What truth could they add here? They could add more details or make excuses, but that waters down the message - the point isn't "Linus did something bad and made factual mistakes", it's "Linus has shown a pattern of doing bad things, and frequently publishes factually incorrect figures"

I think you're coming at it from a place of "you have to give them a chance to respond out of fairness", but journalism isn't about fairness, it's about distilling an easily consumed message from the endless complicated facts that make up any situation. Journalistic integrity is about making every effort to give a "good take", and should put accuracy above all

Being fair to the people you're covering should follow naturally by pursuing the truth, doing the opposite is what we call "softball journalism"
