Because that’s a primary source which Wikipedia tries to avoid. Obviously this can get quite weird, but good luck arguing with a wiki rules lawyer fixated on that. People are often more reasonable than that though.
If I'm writing an article about you from scratch then I'd want to look for sources, to see if you're notable - etc. But if I was updating an existing article and just trying to find a source for your address it would seem easier to take it from your website than wait for a third party to write about it. At some point ideological purity gets in the way of practicality. And there's no need, you could easily tag first-party data so it could be audited and replaced.
If Wikipedia had an article about every start up company, every product, and every software application, it would be filled with unmaintainable / uncheckable marketing spam. (To an extent it already is.) Wikipedia’s goal is to be an encyclopedia, not a software project directory.
Note that there’s a somewhat different standard between establishing notability vs. verifying particular claims in article content. Primary sources can sometimes be used for the latter. But it’s also plausible that the Signal article doesn’t establish all of its claims to the satisfaction of Wikipedia guidelines.
The criteria are that the coverage is “significant” (i.e. more than just a throwaway mention) and made in “reliable sources” that are independent of the subject of the article. This certainly includes peer-reviewed papers. For examples of reliable sources, see https://en.wikipedia.org/wiki/WP:SOURCETYPES
I don’t understand what you are getting at with “... next to historic and outdated 20 yo material...”

Once notability for the main topic has been established, the criteria for validating specific claims is a bit looser. For example a company’s own website could be used to demonstrate the current version number of a piece of software, a press release (or even a tweet) could be quoted to describe the company’s first-party response to some event, an arxiv preprint from a tenured scientist or mathematician could be used to support some mathematical formula, a blog post by a living person could be used to validate their birthday or the name of their spouse, and the like.
(For example, in 2005 Google made up a brand new prize to award to Ruby on Rails creator David Heinemeier Hansson expressly for the purpose of padding out his O-1 visa application to move to the USA. Does that mean the O-1 visa requirements/criteria are bullshit? Maybe.)
(a) Wikipedia notability guidelines can certainly be gamed to some extent by motivated self-promoters who are willing to jump through hoops to place their pet topics in newspaper articles, research papers, published books, etc.
(b) Sometimes Wikipedia ends up rejecting topics that should be included based on a lack of sufficient third-party write-ups in secondary sources.
But Wikipedia still has to have some kind of guideline to prevent itself from being flooded with self-promotion spam, and the current notability guidelines and reliable source guidelines work better than many suggested alternatives.
you're conflating two different things. the sources required to establish notability are different than those than can be used to say something more mundane, like when something was released. it's a higher bar. a product's own website can be a source for basic things, but it can't be a source to establish that it's notable.
> Comment: github, medium, app stores are not sources. Not seeing any indication of notabilty, just an ad [Slywriter]
I think Sylwriter reached the right conclusion but for the wrong reasons. I also think it would have been polite to write a more substantive message considering the amount of work that clearly went into the draft.
Edit: I read the article more careful and I now think Sylwriter was wrong and didn't read the article carefully.
The article cites to articles published in NDTV Gadgets 360, itsfoss, MUO, Fossbytes, TWN Plugged, RestorePrivacy, and Cointelegraph. I'm not familiar with Wikipedia policy enough to say whether in this context these sources count. However, Sylwriter should obviously have addressed them. They're not "GitHub, medium", they're secondary sources in publications that are okay by the standards of software reviews and poor by the standards of something like the New York Times.
Saying the article fails due to only primary sources when it has secondary sources is flat wrong, though. Simply reading the list of references would have cleared this up. Despite volume I find that inexcusable. I'd expect a reviewer to at a minimum read the first few hundred words and then skip to the generated references list and skim for source type.

My current wikipedia pet peeve:
Session Private Messenger[0] is absent from Wikipedia's comparison of cross-platform instant messaging clients[1] because it doesn't have a wikipedia entry. Session does not have a Wikipedia entry, despite having a well-sourced draft[2] because "github, medium, app stores are not sources".
I note that github is cited throughout the Wikipedia entry for Signal messenger[3]. Furthermore, why is Session's page on the Apple App Store not a valid source for the claim that Session is available on the Apple App Store?
