Disinformation should not be regarded as protected speech, any more than a fraudulent product claim or a defamatory comment is. Same goes for statements intended to incite stochastic terrorism, or specific and actionable death threats, or foreign propaganda emanating from troll farms.

Unless you are so stupid as to do nothing but repeat such malicious content, you free speech rights are not infringed by controlling malicious, false, toxic targeted claims such as those. And you are free to moan about it all you like, but it is becoming an existential matter for the preservation of democracy that such content is dealt with decisively. We're in an information war, and the people originating that bullshit are this generation's Lord Haw Haw and Tokyo Rose.
