The term freedom of speech usually alludes to the first amendment of the U.S. constitution, which talks about the right to articulate one's opinions and ideas without fear of government retaliation or censorship.
Private entities and private spaces are not required to protect your speech. The first amendment does not protect what you say— only your right to speak.
This means that you can say what you choose, but the nature of free speech is that others are free to say what they choose, whether by disagreeing with you or rounding up a bunch of people to respond to you.
Free speech does not mean one can speak without social consequence.
Many use Free Speech (especially on the internet) as a guise to be antagonistic and hostile. In these cases, being silenced with a ban is retaliation for being an asshole in public not suppression of free speech.
Online social spaces are real social spaces.
