That's an interesting proposal. I think that people who want to be digitally literate are, and the people who aren't haven't chosen to become so. I'm not sure that kind of campaign is going to solve the problem.
It is tricky to say that government should regulate the media. I agree with what you said about there being free and independent media. I think, rather, we should look at what media the government is funding and ensure that the funding aligns with these values. Making intentional efforts to create media that support these values is a good investment, but not necessarily policing all media.
