This is the paradox of public space: even if everyone knows an unpleasant fact, saying it in public changes everything. One of the first measures taken by the new Bolshevik government in 1918 was to make public the entire corpus of tsarist secret diplomacy, all the secret agreements, the secret clauses of public agreements etc. There too the target was the entire functioning of the state apparatuses of power.
