Since when is an individual's personal blog "journalism", and therefore expected to live up to that standard?
If the author is going to pretend to be a journalist of a security researcher, I see no problem holding their work to the ethical standards expected from those sorts of people.
Expected and therefore commented that it's chickenshit when it doesn't happen? Yeah, no. If this were a reputable news outlet, that expectation would be reasonable.
Requesting comments were only a formality to address already voiced concerns
