I think you mean the OSI (Open Systems Interconnect) stack, and it "came out" much earlier than 2006. I remember working with it myself in the early 90s. It's also inaccurate to say it was a clone of TCP/IP since many parts of that beyond simple packet formats (e.g. congestion control and routing) were still very much in flux at that time. Innovations were being made on both sides, and often transferred between the two. This was a time when DECnet and NetWare were still in use, and they also had their own heritage separate from TCP/IP. IETF was not the origin of every networking thought ever. But you're right that this is mostly about telecom folks not getting over their loss in the circuit-switched vs. packet-switched war, and that chewing off limbs would be preferable to working with ITU-specific standards again. ;)
