For plenty of people something like the weather or the government really is the reason they moved.
The government was a major reason for my move. I moved after the collapse, which was entirely caused by Iceland's dysfunctional government policies (none of which have really changed), and the measures put into place post-collapse largely benefited homeowners at the expense of the rest of us.
I didn't want to spend the next decade paying for other people's bad financial decisions at the cost of the currency & my purchasing power having fallen around 1/2.
Similarly people move from say the UK to Spain for the weather. As I'm sure you know Iceland doesn't just have "bad" weather, it's on a whole different level where working around the weather often becomes a major logistical difficulty. Whole towns often become snowed in during the winter.
So it's hardly a surprise that someone would move just to be rid of that.
