You mean, because it would actually be _used_ somewhere in open source distributions (that is, not just deep inside some de-facto proprietary half-closed-source fork owned by a single mega-corp)? Yeah when things are hidden away in some cupboard in the basement it's much easier not to ruffle feathers. But yeah the LKML is bad today, but back then it was a veritable open-air cesspool
