The problem with QWACs and eSTAZI is a saturation attack by govt. against people. If Mozilla will display that message it will need to do it on all connections with QWACs, and 99.99% will be safe, initially. So govt. can demand them to remove misleading message. And Mozilla can't detect when govt. will use their CA to do a MITM attack on their political opposition and display message only then.
