Qihoo 360 actually does have a lot of contribution to security, for one: they upstreamed a lot of patches to AOSP: https://source.android.com/s/results/?q=%22Qihoo+360%22
The most recent case is that they broadcast the footages captured on the so called security cameras on a website that it positioned to be something like Twitch but with daily life content. So you really got to see inside other people's house! Supposedly this needs to be enabled by the user as an option, but I'm not sure why so many people enabled it. They have stopped this 'service', without admitting that it's wrong.
My hands shake out of anger when I'm typing this.
