Isn't focusing on what's proven false better than attempting to determine what is true? Are you saying it's impossible to determine if something proven objectively false is false?
Also it's worth point no arbitration of "true/false" occurred, the use cases were fraud spamming etc.
A Department of Disinformation is totally different. We're not trying to define what truth is, we're trying to define what it isn't, which is absolutely not equivalent. If you say it is equivalent, you will be banned for spreading disinformation.
