I don't pretend to speak for them, but I'd hazard most of the Europeans would strenuously disagree with you. They don't even get the option of an extra bonus gift.
As for trusting someone on the internet, I've yet to be burned when it comes to folks on this site, and I've run over a half-dozen Secret Santa events which involved literally hundreds of people. Besides, even if you get burned, what do you care? Your extra gift is completely meaningless to you: you lose nothing.
Finally, I guess where we differ is our level of entitlement. I bought my way to Platinum status because there were enough games they offered that I spent the money to play said games. I never once spent a penny solely, primarily, or even partly due to Club Nintendo. Heck, a large chunk of my coins came from games I downloaded via Club Nintendo, so without those freebies I wouldn't have made Platinum at all.
I reserve the right to be disappointed in the extra goodie of course, human psychology being what it is, but I'm not going to be angry or upset that the year end freebie isn't of much use. If I was, I'd have stopped registering games years ago: I never listened to the Majora's Mask CD, or used my Nintendo Playing Cards, and the calendars are useless to me. But that's alright: I spent money to get games I wanted to play, use some of the points acquired by said purchases to get additional free digital games that I wanted to play, and now I got an additional freebie on top of that, one which didn't cost me a single coin. It's the cherry on my sundae, and even if I don't like it it doesn't spoil my dessert at all.
Your mileage may vary.
