Okay, she's clearly talking about misinformation as it relates to public health. Do you think it should be up to the individual companies to discern the same dozen or so identifiable sources of anti-vax propaganda that's getting people needlessly killed?
As others have pointed out in this thread, "misinformation" has easily extended to politically inconvenient facts, such as the lab leak theory. The government absolutely does not, and should not, have the authority to censor what it deems to be misinformation. The fact that the government is directly coordinating censorship of a highly political subject absolutely discredits the notion that these are just private companies executing "corporate freedom of speech". It is a flagrant violation of the first ammendment at this point.
Saddam Hussein not having WMDs and the Iraq War being based on false pretenses was considered misinformation under Bush. NSA mass surveillance was considered misinformation under Obama. Climate change was considered misinformation under Trump. You are advocating for a "ministry of truth" to enforce the official government narrative. People need to be allowed to discuss these things, because the US federal government's track record for being a purely truthful, altruistic entity is quite poor.
