Does YouTube censor conservative viewpoints?

Internet users can find just about anything on YouTube, even videos they don’t want to see. For that reason, users have the option to set YouTube to “restricted mode” with just a few clicks. It isn’t even necessary to sign in to make this adjustment. Many users, especially parents, are happy with this setting. Conservative educational site Prager University (PragerU) is not.

Is it about free speech? Or just money?
