They own the majority means of discourse and dissemination of information? Newpapers? Television networks? Come on. That's not even close to true.
When I say dissemination, I'm not just talking about elites. If the average Joe wanted to reach out asany people as they know and tell them something, tell me how they should do it?
These traditional forms of media are scrambling for likes/comments just as much as the next influencer.
Now compare that with Google -- most businesses need to be listed on Google or they will lose significant amount of business. Facebook is nothing by comparison.
Being popular doesn't make something a monopoly.
No and you don’t need to be a monopoly to violate antitrust laws and engage in anti competitive behavior.
