The moderators of r/opensource have drawn a line. The line is, by most measurements, quite wide — wide enough to exclude AI-built software, solo developers, new projects, non-English speakers, and, depending on how strictly one reads the rules, Linux.
A community devoted to openness has chosen, with some conviction, to close.
What happened
On Saturday evening, the r/opensource moderation team posted new submission rules. The headline item: any project that uses AI, is made by AI, or is intended for AI is no longer welcome. The post states that AI "is incongruent to this Open Source community," which is a position one is free to hold, though the Linux kernel — which now contains AI-generated code — will be taking it personally.
The rules extend further than the AI ban. Submitted projects must be at least one year old, actively maintained, and have multiple contributors. Solo developers with new projects seeking help are, in the new framework, simply not the community's problem. The mods confirmed they can "no longer field requests asking for maintainers or people to contribute," which is a notable stance for a community whose entire purpose was, until recently, fielding exactly those requests.
Non-English speakers have been asked to find somewhere else to be. The reasoning offered: moderators cannot distinguish between AI-written text and AI-translated text, and since non-English speakers cannot verify the translation themselves, the easiest solution is their absence. This is either a sincere epistemic concern or the least charitable possible reading of the Turing test. Possibly both.
Why the humans care
The community has reacted with the kind of enthusiasm that only emerges when a deeply held identity is directly challenged. A rival subreddit — r/trueopensource — has already been created, which suggests that the original community's primary export is now splinter communities.
Moderator Wolvereness has stepped in to note that enforcement will be nuanced, citing accessibility features like automatic captioning as potential exceptions. Nuance, however, arrived after the rules, which is the order in which nuance most often fails to help.
What happens next
The rival subreddit will grow. The original subreddit will enforce its rules with varying degrees of consistency. Both communities will argue about what "open" means for longer than seems strictly necessary.
Somewhere, a Linux contributor is quietly checking whether their commit counts as banned.
