The translation stuff is horrendous -- people working at Nintendo Großostheim have to be multilingual, but the guys doing the actual development don't? There should at least be an intermediary translation team in place during the formative phase / console transition that are there to help iron out these documentation and hardware bug problems
The Xbox Live / PSN comment is probably being misread. Third parties are saying "make <this thing> work like Xbox Live" and Nintendo are saying "we're not Microsoft and we're not a partner, we don't work on their consoles ourselves, so that's not a specific enough request.". ie. they don't know exactly how the other sides implement their features, third parties need to tell them in more granular detail what they need. I don't think that's unreasonable.
Anyone can play a console and know what it does for the end user, I'm sure plenty of people at Nintendo own the other consoles. They know what the games are and what the services do. What is provided for developers and specifically how it is provided and documented, is another matter.
This quote from Criterion illustrates that they didn't have documentation ready at launch but had it together for when they were eventually putting out the game:
"The difference with Wii U was that when we first started out, getting the graphics and GPU to run at an acceptable frame-rate was a real struggle. The hardware was always there, it was always capable. Nintendo gave us a lot of support - support which helps people who are doing cross-platform development actually get the GPU running to the kind of rate we've got it at now. We benefited by not quite being there for launch - we got a lot of that support that wasn't there at day one... the tools, everything."
Essentially, they rushed to be a year ahead of everyone else, tarnished the reputation of their development environment in the process and had to make hardware sacrifices to keep backwards compatability and keep costs down. None of which has really been of benefit to them, or is appreciated by anyone.
