The Powers that Be

There has been a bit of a rush off of Livejournal of late, with the revelation that the LJ servers have been moved to Russia. The thing that slightly perplexes me about this is why having your data stored in Russia is necessarily worse than having your data stored in America. In both cases, your data is at the mercy of a large foreign power with a questionable record on privacy. In the case of America, however, there are a whole bunch of mutual co-operation treaties that are likely to make it easier for the UK government to get their hands on the data.

Now I don't suggest that the American government is as totalitarian as Russia (yet), but I am honestly having trouble seeing a qualitative difference in the risk profile of using LJ now it's a Russian rather than an American service. Is there some sort of cognitive bias at work here?
