IMO free speech requires moderation, but the "how" is an unsolved problem. In a completely unmoderated environment, free speech will be drowned out by propaganda from your adversaries. The decades of experience and the industrial scale that Russian (or similar) troll factories can manufacture grassroots content or fund influencers is not something that can be combated at an individual level.

It would be a mistake to think such operations care too much about specific talking points, the goal is to drown out moderate discussion to replace it with flamewars. It's a numbers game, so they'll push in hundreds of different directions until they find something that sticks and also both sides of the same conflict.
