If they had said that instead of "lied to congress" they would have lost less credibility with this reader. But then they wouldn't have gotten the click.

The word "lied" has a lot of layers[0] other than "knowingly said an outright falsehood". He may not have told an outright, provable falsehood (although some of these examples are close). He certainly has a long history of statements to Congress that are baldly misleading or belied by Meta's own internal records.
