It might not be a bad idea to to set up media ownership rules that exclude entities that are based-in or controlled by non-democratic regimes.
Of course no-one can argue against it if you re-state it like that. But the paradox goes much further: "Popper asserted that to allow freedom of speech to those who would use it to eliminate the very principle upon which they rely is paradoxical."
The paradox implies it because if the ideas of tolerance are so fragile, that even in a majority tolerant society, intolerant ideas present such a threat as to consider sacrificing even free speech, then how could they have ever come to dominate in the first place?
