It is inarguably worthy of mention in the biography of their life to date, and extremely unlikely to be downgraded to an unimportant side detail in the final version.
Wikipedia is indeed neither an encyclopedia or a newpaper. However its attempts to be one at the preference of not being the other, are analogous enough to the real world distinction, for us to be able to mock and castigate them when they get it so, so, wrong.
What we do know about Wikipedia, from this incident, is that it is just shit as an information source, be that newspaper, encyclopedia, or some hybrid of the two. Specifically, it wants people to think they are benefiting from having a place to go, somewhere with the top Google rank for this person's name, where they can supposedly find a summary of their life, and links to further useful information sources, like their Twitter feed.
Currently, for reasons which are just fucking stupid and bear no relation to their actual policies surrounding such things, Wikipedia evidently wants readers to still believe Manning is running for the US senate, with a primary scheduled in 22 days. It does not want readers to have any clue as to why their Twitter feed doesn't exactly reflect that as her current reality.
There is of course an up to date reliable source which at least confirms the campaign is still a thing in light of recent events, even if that is basically just a lie, but they can't really use it in the article because it is all part of the same news coverage discussing the incident they seem to think is too trivial, too damaging or simply not eligible for an encyclopedia because it is mere news, as if all news is excluded by definition. A situation proved quite false by one look at the article's references.
These people are dickheads. Wikipedia protects them from facing that harsh reality by excluding all the voices of people who aren't stupid enough to engage with this farce on a long term basis. And in truth most of their nominal readers don't care because they no longer actually use Wikipedia as an information source. And why would they? Whatever they call this thing they have cobbled together with Chelsea Manning's name at the top of it, as a result of this incident, why would anyone bother to read it, for any purpose. Nobody has any clue how they decide what goes in and what stays out. A look at the talk page just confirms the nominal process is to just talk utter bollocks, until people get tired of talking bollocks.
A hilarious side effect of this farce, is that they were unable to add this latest news in a timely fashion either......
https://reason.com/volokh/2018/06/01/ch ... s-first-am....and readers will actually struggle to find that on their news feed of choice, since it is obviously not considered the most important thing going on in Manning's life right now. She may not even know of it herself, given her mental state. But readers of Wikipedia cannot be provided any such context. Because of these dickheads.
Still, assume good faith, we are being asked, by said dickheads. Well, the world probably already appreciates that stupid people can do stupid things with the best of intentions, but they might not know that one of the gifts of Wikipedia to the world, is that is now a part of the encyclopedia writing process. Supposedly.
Given Wikipedia's political bias problem, despite their protestations, the most obvious explanation for this farce is that the article is being controlled by partisan editors who don't want Manning to be seen as unstable or unelectable, and don't want people thinking her campaign has come to a shuddering halt.
