We want the population to be well informed. But when you consider the history of literacy, journalism, and what media most people have access towards, that assumption was never really true in the first place. People were always getting propagandized as soon as they had the power to vote or even merely chose among suppliers. Probably long before that too.

>We want the population to be well informed.

Who is "we" though? The elites with interests counter to what's best for the people, for example, surely want the opposite.
