The 'way you see it' is detached from reality, even most "free" Linux distros may contain non-free software or propriety closed-source kernel blobs, despite GNU's guidelines.

About every company, Chinese and non-Chinese alike, includes proprietary software, paid services and copyrighted content like ringtones and wallpapers. If you wish to change the world, go ahead, just not here.
