Why a Data Disclosure Law is (Likely) Unconstitutional

Social media platforms have changed the very structure of communication. These platforms exert significant influence over how we get our news, how we form and join political movements, and how we connect with friends and family. But social media platforms are black boxes. Moderation algorithms are opaque--even to the platforms themselves—and attempts by third parties to research these algorithms are often frustrated. Because platforms withhold data necessary for public interest research, Congress might step in and mandate data access for certain researchers and journalists. I conclude that any such effort would (likely) be unconstitutional under the First Amendment.
