Interesting data, but I fail to see anything sinister going on here. Skimming through the list, it looks like 90% of the articles fall into one of three categories: Streets in Oslo, embassies in Oslo and people I mostly haven't heard of (i.e. not politically controversial characters). I don't see any edits intended to sway public opinion.
Same here, my only worry is that maybe that's exactly the strategy they use to blur the waters. On the other hand, propaganda can't be that forward, can it?
