I'd wager a movie on a mass distribution platform like Netflix is going to be more effective at making people aware of the problem and help them mitigate its effects on an individual basis... than, say, trying to change the way capital flows.
My point is that it’s easy to make an argument about this aspect of SM than to talk about the money, trace it, and pinpoint blame. Nowadays, there is plenty of evidence available about the psychological effects/harm of social media. So it’s easy/harmless to fund this kind of exposition than anything that talks about the finance side.
