Hmm. If i look at the slides, the article should be renamed "gstreamer, and some stuff browsers on all platforms do, are insecure"? Is it easier to change your media player on Linux, or to trust Microsoft? Say, does a default Windows install still enable 20 networked services that don't belong on a home computer and can be exploited without the user downloading anything?
My default installation came with VLC, firefox and KDE. No gstreamer nor gnome installed, google products including Chrome are not welcome. Though I'm pretty sure manjaro is part of the Desktop Linux family.
Too bad this misrepresentation is hurting the message OP is trying to carry to the world. Then this message is hardly news, the guys at grsecurity have been at it for 15 years providing hardening security patches to the vanilla kernel.
