That's unsurprising. There's no willingness to challenge the Nobel Foundation on the basis set out by Assange, even though they themselves reluctantly admitted in 2012 that they have a duty to ensure the will is respected:
> "...pursuant to the current legislation governing foundations, the Board of Directors of the Nobel Foundation is legally accountable for ensuring that [...] the Nobel Peace Prize is awarded in accordance with the criteria stipulated by Alfred Nobel."
This was from a press release from 2012 that now appears to be deleted from their site: https://web.archive.org/web/20120601234000/http://www.nobelp...
I think a serious examination of Nobel's will and how the Nobel Committee chose Machado over other candidates would make the Norwegian Committee look very bad. It would also show that the Swedish Nobel Foundation failed in its legal duty to ensure the will was respected. A result that would embarrass both Norway and Sweden. So what you get instead is quick dismissal of any such complaints.
The Swedish press has also been terrible in reporting this. I saw articles trying to make Assange out to be stupid for filing in Sweden. Journalists either didn't bother reading the Wikileaks press release, or wanted to keep their readers in the dark about it.
Here's one example from Aftonbladet (Sweden's largest news site):
> WikiLeaks alleges that Assange sent his letter to Swedish authorities, although it is the Norwegian Nobel Committee that appoints peace laureates. ("Wikileaks påstår att Assange skickat sitt brev till svenska myndigheter, även om det är den norska Nobelkommittén som utser fredspristagare.")
There's a book by Norwegian lawyer Fredrik Heffermehl that goes into the 2012 challenge to the Nobel Foundation. I've only skimmed it, but looks quite interesting: The Real Nobel Peace Prize - A Squandered Opportunity to Abolish War https://www.kobo.com/se/en/ebook/the-real-nobel-peace-prize-...
