Moderator Wolvereness announced over the weekend that r/opensource now bars any project that uses AI, was created with AI, or is intended for AI applications.

"AI, as it exists today, is incongruent to this Open Source community," the moderator wrote, adding: "Tokens are cheap, and we don't care how many you spent to make your amazing project." Tools built for AI, such as MCP servers, are also out.

By Monday the announcement had drawn roughly 2,700 comments and a net score of zero, per The Next Web.

The crackdown goes well beyond AI. Projects promoted on the forum must now be actively maintained for at least a year, have an established community, an OSI-approved open-source license and at least three contributors, give or take.

Common student projects like note-taking apps and PDF viewers are excluded, and developers can no longer use the subreddit to recruit maintainers or contributors.

Posters need a Reddit account at least a year old with a history of significant contributions, and anyone who tries to post and then asks moderators for an exception risks a permanent ban and mute — Wolvereness said roughly 20 such messages arrive a day, reports The Next Web.

The most eyebrow-raising restriction concerns language: "If you don't speak English, you need to find a different community." Moderators argue they cannot distinguish AI-written English from AI-translated text, and that non-English speakers cannot verify whether a translation is accurate.

One commenter called the hostility toward non-English speakers "disgusting," Tom's Hardware reports.

Fellow moderator ssddanbrown publicly objected, saying they had not been consulted and only learned of the changes through moderation notifications: "I don't agree with that rule. Especially so with how it was it was said."

HotHardware suggests users could instead post in their original language alongside a translation.

Even projects with no AI involvement can fall foul of the rules. One user pointed out that their nine-year-old project, with more than 300 GitHub stars and dozens of resolved issues, no longer qualifies because they are its sole contributor.

Independent developers now seemingly need an established community before they can use an open-source forum to find one. The rules also create awkward questions for the Linux kernel, which allows AI-assisted contributions while holding developers responsible for the code.

Wolvereness said the kernel would probably still pass "the subjective line," and acknowledged: "There's no 'objective' way to implement this policy."

The row lands amid a broader fracture over AI-generated contributions.

System76 has banned AI-generated code from its COSMIC desktop project, parts of GNOME have similar restrictions while other GNOME developers question rejecting AI-discovered security vulnerabilities, and the debate has caused rifts within KDE.

Per The Register, NetBSD has emerged as an AI-free alternative, while Linus Torvalds argues competent developers should be free to use AI tools but warns against low-effort 'drive-by' patches.

Maintainability pain is real: cURL, tldraw, Node.js and OCaml have all faced questionable AI-generated bug reports or large patches, Tom's Hardware notes.

The backlash has already spawned rival communities, including r/TrueOpenSource and r/OpenSourceAIAllowed, and the original announcement was updated to point disgruntled users toward them.

Wolvereness blamed part of the reaction on an X post that directed hundreds of people to the thread, The Next Web reports.

Ultimately, r/opensource is a Reddit community, not an authority on what qualifies as open source: moderators are free to decide what gets posted, and developers are free to take their projects elsewhere — which is exactly where some of them are now heading.
