The ITU is basically All The Legacy Telcos, who are still miffed that the ever-so-elegant OSI protocol stack [/sarcasm] lost out to a bunch of neckbeards who actually did *engineering*, and have been trying to claw back some validity ever since. "rough consensus & running code" >>>> kilopage specs with zero interoperability.
[ I was *at* AT&T late 80s, they had an OSI package for their nascent 3B midrange line, and a third-party TCP stack for 'transitional purposes'. Shocked the feces out of them when World+Dog ignored the former, even/especially inhouse... ]
