Tucker Carlson is specifically cited as maintaining that he spoke the truth on page 5. Rather it's Fox News that argues that Tucker Carlson was stating an opinion with hyperbole for effect:
"Fox News first argues that, viewed in context, Mr. Carlson cannot be understood to have been stating facts, but instead that he was delivering an opinion using hyperbole for effect...
This “general tenor” of the show should then inform a viewer that he is not “stating actual facts” about the topics he discusses and is instead engaging in “exaggeration” and “non-literal commentary.”"
At any rate, the case is a lot more complex than just one guy claiming no one believes anything he says. Using it to justify the possibility that the interview by Tucker Carlson was not with the actual Sam Bankman-Fried by with a potential imposter or AI is absolute bonkers.
