Would it be more accurate to describe search/social media platforms as Marketing Mechanisms that solicit user-created search/content to generate revenues rather than as "media" platforms? The distinction is critical, for "free speech" is not a blanket carte blanche for marketing. If we remove search/social media from the category of "media" and create a new category Digital Marketing Mechanisms (DMM), then this new category necessarily requires a new regulatory structure and very different legal interpretations and protections of "free speech." The definition makes the world of difference. Which do you think social media is?
