The article describes the fact that the CM Browser ignores certificate errors and shows websites as though they were properly secured. Having an actual proper setup (with a trusted CA etc.) wouldn't help here, because a MITM attack would not be visible, because the middle man's certificate would be shown as valid in any case.

I assume Tencent's QQ Browser validates certificates properly, but combined with a horrible RSA implementation that's not worth anything. It's actually a more clever (less visible) way of pretending to establish secure/authenticated connections.
