The only thing I would add to that statement, which I agree with, is that Norway, aside from whatever internal disciplines it has and whatever WTO-related disciplines apply in this situation, is also a member of the European Economic Area, which includes the EU countries, Norway, Iceland.... They also have disciplines in this area.
One of the citations from Norway's own public accounts documents from some years ago indicated--and this was in the context of the winding down of the subsidies initially in 2003, and then there was a two-year transition program until 2005, which is the date that David referenced in his comments just now--that financial assistance would no longer be permissible under EEA rules. So I just mention that there is that additional layer of discipline that applies to Norway in this context.
