That seems like an abuse of political power though. That policy would result in limiting exposure of views that are controversial or disagreeable to progressives, since Facebook/Twitter/Reddit/etc. clearly have a highly progressive employee base and moderation policies built around that worldview. Effectively, isolating exposure of some content in this way would tilt the political scales by only allowing other competing (un-isolated) views to benefit from network effects. That to me feels a lot like propaganda and it doesn't make it any more acceptable or holier that it is done by a domestic tech giant rather than a foreign state power.
