Because that's what the President of the United States should aspire to be like, the most brutal dictators in the world.
That isn't the point at all of course. The idea is that deranged people make absurd comparisons. Just like when someone does something bad but not genocidal and people call them 'literally Hitler' you know they are being absurd. The absurdity of calling Trump the global press oppressor when other regimes actively MURDER journalists is worth mockery.
