> Dictatorial regimes that implement actually beneficial policies I can tolerate. Less good than a democracy in terms of social and political freedom, but better than dictatorships that don't implement any benign policies.

The policies are not really the problem actually, especially when they are, as you say, beneficial. In a perfect world where media coverage respects basic ethical rules of journalism, there shouldn't be any issue really. Unfortunately, in the case of Rwanda, I tend to see the magnifying glass systematically being put on 'favorable' PR-stuff like that, vs constitutional reform, mysterious disappearances of political dissidents of the regime (sometimes abroad), open support to militias in Congo. e.g: I wonder what someone on the receiving end of bullets in the Kivu region would think of the hagiographic article of the guardian.

Ultimately, the survival of most of this kind of regime depends heavily on the way they are perceived globally, undoubtedly, the Rwandan regime beautifully manufactures its image.
