Their citizens are perceived to be the least desirable EU citizens to have as immigrants.
Or why wouldn't they go in the slightly-less-richer, but culturally closer Spain or Italy? Especially since the weather is much nicer over there :)
Those things might exist in other countries, I don't know of them personally, but I do know that moving to Finland is non-trivial. The language is hard, and unless you speak it you've only got unskilled jobs to find - with high competition. Gaining residency pretty much necessitates having a job too, which makes it all a bit circular.
I'm settled here for the foreseeable future, although I have to wait another couple of years before I qualify for citizenship.
But the article is not about people from hacker news, it's about any EU citizen.
