The English version isn't particularly free. I attempted to add a page about a file format that is fairly well used but doesn't have a huge amount of information online about it. The only real source is a zip file from a companies website which contains a pdf with the file spec and some example programs. Unfortunately the editors decided that due to the lack of referencable sources, they would rather no article exist at all.
I understand it for some cases where the mods just need to stop people making up random crap on topics that don't exist or can't be verified. But in this case a single reference is more than enough to write the whole page because the spec is literally the only source of truth on the topic.
Unfortunately I think the mods may be too passionate about "protecting the integrity of wikipedia" that they let legitimate content be deleted. It also doesn't help that the wikipedia UI for disputes and edits is really confusing and I had a hard time trying to work out what was going on or how I communicate to this moderator. The whole system is designed for power users only.
It's important to note that there are not only "the mods", but two opposing factions in Wikipedia: the Deletionists and the Inclusionists. [1]
I too agree that we don't need articles on someone's cat, but I've had articles deleted as not notable on indie web comics and indie role-playing games with hundreds or thousands of readers or copies sold.
I thought that the fact that the RPG was published and publicly available, and was being discussed in RPG forums would make it notable enough, especially when it was mentioned as an inspiration for rules in more traditional RPGs. But since they hadn't been mentioned in any published articles they were deleted and there was no real way for me to fight it. I had added stuff like the list of contributors, publishing year, and overview of the rules and setting, with no personal discussion of the game.
The result was that I stopped trying to improve Wikipedia, because I don't have the time or interest to fight people with an infinite amount of time that deletes my additions. My main contribution to Wikipedia wouldn't have been on the articles on Barack Obama or World War II anyway, as they already have people who are experts that add information. I could have brought information on my specialized topics of interest, but realized that they would all seem non-notable to someone who's not interested in the same thing and would be deleted.
Fileformats.info is a thing. You could try and add it to their wiki, then you would have a "reliable" source for the English Wikpedia. Specialized websites are usually considered "reliable" for that purpose.
I actually did reference a user created page on the OSM wiki about the format which matched what the official docs said. But was told that wikis are not a referencable source for wikipedia.
