As I was reading, I was asking just that; why can't other fields just do the same thing? The scoap initiative is funded by CERN, which is funded by 21 states so i suppose in the grand scheme, Particle physics is a small blip in the pockets of these governments compared to, say, Pharma or conservation so yeah, maybe its the scalability that's an issue.
I'd like to prioritize the accessibility to mainstream audiences via social media though above financial aspects I think; aside from popsci videos you might casually scroll past on facebook, this is an underperforming aspect of society in my opinion
Then you may need some double stream: science for scientists and those we want, and science for anyone. No?
