It's not the ITU that's trying to control the internet
It's a bunch of governments that want to control the internet by any means necessary. This includes, curiously, the USoA, though they use tricks a little different from the rest. They already do control the internet and only need to maintain the status quo to keep it. China, Russia, India, and so on, think it time for themselves to own a piece of that pie, and if they can't get at it individually, well, why not use a toothless proxy like, oh, the ITU maybe.
That is to say, the problem is real but the remedy isn't working.
