I never said what you're resenting, nor meant to imply it.
But IETF, with their emphasis on practicality, on "rough consensus and running code", was far more on the agile end of the spectrum than OSI was. IETF would recognize a problem, have an RFC, and have working implementations before OSI had done anything. This meant that if you wanted something, your first chance to get it (often by years) was on the IETF road, not on the OSI road. Repeat that a bunch of times and the people who could benefit from new things all moved to the IETF standards.
