Well, I guess Nintendo is mostly to blame for bad/sloppy ports. Bad support. I would be pretty pissed if I couldn't get questions answered from the company if I am making a game on their console.
Nintendo doesn't have translators or english speaking personnel on site?
I understand why 3rd parties are giving it the cold shoulder, it's not worth it to make a game from scratch on a system where 3rd party titles don't fare well, and the only way to make a game great on the Wii U, is to make it from the ground up a Wii U game.
It saddens me to read stuff like this. And I hope Nintendo gets their stuff together. I still love my Wii U and will continue to support it 'til it dies. There's still some great games on the way, and some very spectacular looking ones.
I'm sure not all devs feel this way about the Wii U, and if sales improve don't be surprised to see the same people/devs singing a different tune.
