I wouldn't blame them either now, even though I would say the vast majority of the community likewise was not happy with the link you showed. But, as people have said whenever others have brought this up, this isn't year old historical precedent, it's decade. Don't get me wrong, as I said I understand - but the community that is no longer comprised of the horrible individuals revealed during this past summer (and prior), has 0 expectations for Nintendo to ever act. They never have, and unlikely ever will. Would love to be proven wrong, of course.
I'm also of the personal opinion that Nintendo's lack of involvement made the scene all the more shady due to the local focus, and that directly, without a doubt, lead to the horrible people we all know being prominent. No officials, no systems for bans/reporting conduct, nothing - because the scenes were relegated to locals for tremendously long.
