From the website:
About ITU. ITU is the leading United Nations agency for information and communication technology. For nearly 150 years, ITU has coordinated the shared global use of the radio spectrum, promoted international cooperation in assigning satellite orbits ... ITU is committed to connecting the world.
Nearly 150 years doing what? ITU was founded in Paris in 1865 as the International Telegraph Union.
Sounds to me like more empire building from the UN, using an "excuse-me" from Malaysia.
Surely private communication companies can come up with straightforward solutions acceptable to ICAO and airlines that meet ITU approval (if needed).
