There isn't really. You're adopting, I assume, J.S. Mill's view, that the cure for bad speech is more speech, which he famously published in 1859.
However, since then it's been widely accepted that when speech reaches a certain level of harm then the greater good is to prevent/punish it. You can't incite violence under the guise of free speech. You can't advertise that something is safe when it's not. This is because more speech can't undo violence and death after it occurs.
And when it comes to misinformation with regards to provable and intentional lies about voting procedures, election results, etc. that falsely harm the country's institutions and legitimacy, it's entirely consistent for that to fall under the widely-accepted prohibition of speech that rises to a certain threshold of harm. It directly leads to mobs, riots, and revolution based on lies, not based on actual injustices.
This doesn't mean any harmful speech is prohibited -- that's ridiculous. You're generally allowed to insult people, tell lies, etc. But there's a threshold of harm that gets established.
