If you consider the Bloomberg article on SuperMicro, they repeatedly claim expert/insider sources corroborate their version of the story, and have issued no retraction after their story was thoroughly debunked. While this certainly reflects poorly on Bloomberg, it reflects most on the journalistic standards of the article's authors. I don't think we will ever have a world where authoritative sources exist, since there can always be elements within the source of authority willing to bend the truth for more clicks.
