"...I would argue that climate disinformation online is a form of cultural and political malware every bit as threatening to our new media freedoms, used not to foster a forum for open politics but to create, in Nancy Fraser’s term, a “multiplicity of fragmented publics” that harms not only our democracy, but our planet."
Climate disinformation? Harms democracy? Might one point out that Democracy requires freedom to speak plainly in measured and cogent dissent.
