....to ensure that the platform is relevant for the Chinese market...
Exactly which features does the University of Defense Technology consider relevant? Is Canonical enabling repression or military aggression?
Here are the features promised by Canonical to be included in the next two releases or later https://wiki.ubuntu.com/UbuntuKylin Basic stuff, like Chinese Input Method, Chinese Calendar, Taobao and Baidu Search on Dash... nothing special.
If the Chinese populous don't like any of the governments additions, then those users can grab the binaries / source code directly and roll their own customisations.
If the repos are accessible.
And even if they do manage that, then people will just redistribute it offline once one guy has downloaded the content via his proxy / VPN.
It's a bit like when people blame ISPs when customers use their services for piracy. The difficulty of setting up an ISP (or distro) is completely irrelevant in this discussion.
