A valid solution is, of course, authoritarian levels of control over all media outlets. This puts countries like China and Russia at an advantage in this case.

Since most western citizens would object to this, surely middle ground solutions can be found that would prevent abuse and foreign (and domestic) manipulation, while preserving democracy, free speech and individual freedoms. I'm inclined to believe that democracy and authoritarianism doesn't have to be zero-sum, and that a balance can exist that allows societies to prosper even among hostile actors.
