Maybe I'm just stupid, but those calling on Osterdahl to quit will achieve what exactly?
While he may be the exec producer of Eurovision, he won't be the only one calling the shots will he? He's the 'face' of things and with any organisation of this size is most likely following orders from someone else. He might be towing the official line too, but in private disagrees with what is happening for all we know.
It just seems weird to call for his head to go when if change has to happen, its the wider EBU that needs the rethink, not just Martin if you ask me.
I think the main point from all of this to take is that to the wider public, they'll still look at Eurovision as an escape for one night in May and nothing more. They'll come back next year and the year after etc. Whatever people think of this year and the calls for boycotts etc, I imagine that would be such a small minority of the wider viewership it will make no change to the EBU's decision making at all.
