I agree the general meaning would be free to say and do anything, however in reality free speech is freedom of speech from the government. Not individuals or private entities. What is common in law is the idea of the market place of ideas. This is generally what free speech to the average American is. We are free to spread information whether right or wrong in order for others to comment and critique and to grow as citizens. I think it's a horribly slippery slope to ban one group from speaking. You can't have an active conversation about a topic without allowing someone to talk. Their decision is sidestepping the root cause and is treating the symptom which is algorithms optimized for engagement. Misinformation and hysteria is what drives engagement.
