People do not typically talk to their neighbors in Finland in blocks and I have not seen any major change in this regard in the last couple of decades. Indeed, in Helsinki it is becoming a common behavior, before opening the door and leaving, to first look out the peephole to make sure that there isn’t anyone in the corridor – not running into one’s neighbors at all is seen as a common courtesy.

Obviously people living out in Junttila might talk to their neighbors, but these are comparatively so few people that they aren’t representative of the country.
