Okay, so, I'm new in this community and with my hockey-fandom. I guess I am still learning.
Why I decided to give this clarification on the translation was my feeling that a lot of people here are judging a 17-year-old very harshly for words said in an interview right after a disappointing match with some - at least how I read a couple of comments in here as well - questionable penalties stating that they will hate this kid forever and blowing his words out of proportion (my opinion in this case, but only referring to what he actually said and how it is paraphrased here... not to the subject of the penalties itself, because as I said I am new to hockey-fandom and do not believe that I can pass judgement on penalties yet...).
If you watch the interview with an unbiased mind and the ability to actually understand what he says, you will realise that he doesn't want to say anything bad at first, but is pushed into commenting by the reporter and then he kind of beats around the bush in a very calm and hesitant way saying that Canada got all the penalties for playing a certain way the Swedes are not used to and regard as unfair and if the Canucks would have played how hockey is supposed to be played (according to Dahlin) the game might have been different, but "I don't know" (quote Dahlin)... and when asked why Sweden didn't start "diving", too, he simply says: It's not how we play hockey because it does not belong in hockey.
I don't see the odious part here.
As for your last question: there is criticism in Swedish newspapers and television about how the coach handled the situation after the match by not giving an interview.

But Montén is also quoted saying his guys did the best they could and that he is proud of them.
On the other hand there is also an article complaining about the Canadian way of playing, too. So, I would say it was not only the team and its coaches who viewed the refs' job as unfair...
