Although I consider changing the no.wikipedia.org to nb.wikipedia.org the best solution in an ideal world, I'm only in favor of such a change if this does not cause any problems for the project in terms of dead links and such. That would cause the project too much damage. If these problems do arise, the best solution IMO is to revert the label from norsk to norsk bokmål. If we can do this without causing problems for other Norwegian projects using the no code legitimately, that would be gold. But even if that's impossible, I still think chaning the label back to norsk bokmål will be preferable; those other projects are too small compared to no.wiki to outweigh the problems caused by calling no.wiki the Norwegian Wikipedia and nn.wiki the Norwegian nynorsk Wikipedia. As mentioned before, this issue is very sensitive in Norway and if we are limited to next-best solutions, I think this will be the one causing the least harm.

TL;DR: Norwegian has to written standards: bokmål and nynorsk. no.wikipedia.org is Wikipedia for Norwegian bokmål, and it should therefore be called Norsk bokmål as well. Calling no.wikipedia.org Norsk gives the impression that bokmål is Norwegian, while nynorsk is some anomaly. This is not correct, because both are official standards and considered equal.
