There are other factors at play at Wikipedia too. In my native language, Danish, Wikipedia is all but dead. Years ago, I tried contributing within my own field. I researched and spent hours adding relevant information to different topics, only to find out a few days after that all my contributions had been deleted by the administrators.
Here is the Danish site for one of the most beloved Danes: https://da.wikipedia.org/wiki/Michael_Laudrup
Here is the English: https://en.wikipedia.org/wiki/Michael_Laudrup
It's just one example, but it is true for culture, history and many other areas. If you want to know anything on Danish matters, the English Wikipedia is usually a much better option than the Danish.
I attemped to create a page about a slightly obscure file format with all the information I had found while developing with it. I linked to all the sources I found that helped me understand it and my submission was rejected because my sources were not academic enough so I removed those sources and added the only official source in existence which is a zip file containing code examples and example files. My second edit was rejected for not sourcing all of my info.
Literally the only info available is the zip and forum posts. I mainly used the forum posts while learning and verified it against the data I was seeing in the file. How am I meant to share this info for others to benefit from? If I make it in to a blog post it's not an acceptable source but if I post it as a PDF and pretend its some wanky research paper then it probably would get accepted.

While not every topic belongs on Wikipedia, there are a number of other places where your article would be appreciated:
Grandparent said it was rejected because of the citations, not because of any supposed lack of notability. Are you implying that reviewers refuse articles for other reasons than the ones they actually give?
(Edit: from what I gather on this thread, the citations were both secondary and substantial, so the notability criterion was probably met.)
