Sort of the same deal for "what can one do to be a good citizen of the world." That is, "do your best to operate in an ethical way and encourage others to do the same despite how the broader system is constructed."
To be slightly more specific, stuff like finding, using, and publicizing more ethical websites, platforms, and technologies where possible. And most importantly, contribute in whatever way works for you. The web is meant to encourage collaboration and sharing but it has turned largely into a medium to Consume - spend some time Creating things.
Honestly, like fuck Fox News and that dude was just a smug asshole. But at the same time, is he really the one at fault for fucking up that interview?
If this mod were being interviewed by anyone that wasn't already deeply sympathetic to the community were conducting that interview would it really have gone any differently?
