Um, among the "mistakes" Taibbi recently "owned up to" is falsifying information in his Twtter Files reporting. Among other things, he deliberately misrepresented mentions of the non-profit Center for Internet Security (CIS) as the federal Cybersecurity and Infrastructure Security Agency (CISA). It's clear that was not a mistake, but a choice he made in order to further a specific narrative - one that he only admitted when confronted about it. [1]
