This is a simple articulation around something I've wondered for a while. From a regulatory perspective should we be less concerned with regulating the content on the platform (e.g. a single post, copywrited material) and more concerned with regulating the broadcast effect/technology now inherent in all the non-chronological feeds across ad supported social giants (e.g. instagram now put my post in everyone's feed, or trending). There seems to be more than enough precedent in the US around regulating control over broadcast, pre-internet: Limiting TV and newspaper ownership shares, limiting advertising to children and smoking ads, equal time, decency standards -not advocating, just calling out that these things have happened. Some of this I think stems from content being carried on lines deemed "common carrier" (I'm no expert), but the gist seems to be the same here. No one said you couldn't make a movie that included a line with the word "Fuck", but you couldn't broadcast that movie into every American home before the 8 o'clock news.
