Was the Norwegian Prime Minister's post removed because she posted the image again in that post ? This is a crucial question and not clear from the article. If Facebook censored only words then this is a much larger issue. If they censored the whole post (including photo) then while debatable this is Facebook's policy i.e. a blanket ban on such imagery, irrespective of history.
Edit: I don't find it clear journalism, but the fact is there:
Solberg was one of a string of Norwegian politicians who shared the iconic image after Facebook deleted a post from Tom Egeland
So the post was removed because it had the image, not because she had dared to criticize FB.
In the article itself the PM gives Facebook credit for at least being consistent, w.r.t removing posts that contain that photo. So yes, it seems likely it was removed because of that picture.
However, you probably want to think twice before removing a post by any PM. Having done so only fuels the fire, which arguably can be a good thing in this case.
Yes.. I don't like her policies, but she has her good moments, and while I don't think they'll keep reposting it, as they'll have more important things to do, the Minister of Culture has also posted it and had her post taken down, and she has already indicated she very much wants to get Norwegian newspaper editors and Facebook together for a meeting. They'd not do that unless they're very displeased.
