Interesting take. I do not agree.
Helsinki weather is crap. Half a year it is too windy, too wet and too cold to be outside. It rains sleet or snow very often.
Oodi is a great place to do things or just to stop by. No pressure to buy anything. No ads up to your eyeballs.
There are a lot of people just sitting by. Studying. Reading books. Using the provided services. Meeting up people.
The layout is good, especially the second floor that containts most of the services. There are a lot of spaces where you can just _sit_ without obligations.
I am sorry, but I think your ending sentence does not make any sense.
(I am a Finn, I visit Oodi roughly once a week during work trip to the capital).
