I agree it was bad form of the author, but in all fairness the original piece was a very casual editorial and not serious reporting. In objective reporting the standard is to cover all sides of a story, but in editorials it's to spout off your opinion - often with little regard for the truth.
My point is don't trust everything you read, always question the source and intention. A lot of us HNers were also guilty of passing on the blame: https://news.ycombinator.com/item?id=5824276
One more thing: we've now heard two sides of the story (an editorial covering the CCC report and Sean Parker). Keep in mind that we don't know what actually happened yet.
