Nintendo "hate" as it is called often depends on what the claims being made are. There are some claims that are valid to call the Wii U out on, for example Nintendo's complete lack of care for advertising the system, but then there are claims that are dumb such as Nintendo will go bankrupt because of the Wii U. Now something I've noticed here a lot more lately is, unless you say only positive things about any of the consoles, even if it is a valid criticism, then you apparently hate the company's guts and want them to go bankrupt. This applies to
all the consoles and PC, as I've seen Nintendo fans jump on people for not praising Nintendo to the heavens just like how I've seen Sony, Microsoft, and PC fans do the same.
As for the Wii U, right now it is in a very bad situation,
Iwata himself has said that, and it honestly seems like they aren't doing anything to really fix that other than saying "Wii U is in a bad shape and we need to do better." Thing is, we all know Nintendo can do way better with advertising the thing to disspell the notion that the Wii U isn't just an expensive GamePad add-on for the Wii, which is still a problem apparently and Nintendo
even made an add to try and fix any confusion. However, it seems that they've honestly not changed anything much when it comes to it, because advertising for the system is still completely non-existent to the point in which one must question are they even trying at all?
Remember, Nintendo were the ones who gave everyone a plethora of these ads last gen, so they should know how to
advertise:
