I reject the new right-wing orthodox definition of “free speech” which is, essentially: say anything, anywhere, any time you like, as many times as you like, without incurring any consequences.
I think the definition of free speech needs to be refined to account for a little bit more of what Orwell described, which is the freedom to speak the truth specifically.
Add to that the obligation to not be flagrantly abusive of other human beings and their rights.
Add also the obligation to refrain from “spam” however that’s defined: I.e. overly repetitious, off-topic, irrelevant, money-making or self-promoting content.
These are the basic principles of online communication that it seems most social media companies have agreed upon. Whether they enforce those terms or enforce them well is a different story.
