I think that you two drastically underestimate the number of people who are genuinely aware of what good news is and how bad what they are getting is and why. I also think you fail to identify the "type" of person who would participate in a service like this. I don't think the 85 year old Fox News audience is likely to participate much in Elon Musk's project. I think that the people who know what is really going on and where you can and cannot find legitimate credible news are highly likely to participate. I know I would, and I hope that Musk carries through with this.
