Have you heard of Tsarka before? They don't have any press releases from when it started? As others have echoed - could this just be a state sponsored actor?
"I can't help but think if the government were wanting to spread positive propoganda about these tests, your post is exactly what they would write: "everyone wins and everyone is happy with our results of MTIMing the entire country".
Who knows how much information the state hoovered up during this "pilot".
My view of what happened is some clowns at the top wanted a proper, full interception of traffic. Besides the attention in international media it received, people had real issues accessing the internet properly (those who installed). So they simply could not execute their MITM properly. Putting aside privacy, etc. I expected simple operational ineptitude, which is what happened (gladly) and they dropped saying "it was a mere test".
PS, in 2011 the government tried something similar with Google's traffic and after Google started redirecting the KZ traffic they backed, saying some similar B.S. like "it was a test".
