Yeah, seems like this guy only had limited knowledge on the way it works and was regurgitating snippets of things he may have read on the internet. While there are certain things that are theoretically possible, it doesn't apply to the Wii U and how the security now works. He's probably bitter about being reset for boosting or got caught using something he downloaded for the PS3/360.
I just don't get why so many people are so desperate to fear-monger about it. It will likely happen at some point from people who, unlike this guy, actually know what they are doing. But with it will come some very salty tears as the ban hammer crushes them and they lose all access to online and their eShop purchases lol
