Cessation of public development of Kefir C compiler

The creator of the Kefir C compiler has ceased public development and moved the project to private mode, citing unsustainable development effort relative to the project's status and lack of substantive public interest. In a clarification, the developer emphasized that negative interactions, including personal attacks and unmet commitments from the community, along with concerns about code being used for AI training without consent, were primary factors in the decision, while noting that the cessation announcement itself generated more public discourse than the project ever did. Existing publicly available code will remain accessible, and bug reports will continue to be addressed.
