The honest answer is that it isn't the content(RSS feeds), but the combat sport nature of the platform. It's the only place where you can tell a billionaire any kind of awful thing you can think of. It's also the only social media that drives important people insane. The wealthier they are, the more insane they'll be driven.
Facebook will drive your meemaw insane with AI generated ads of legless veterans being given a cake.
Twitter will drive the richest man on earth insane. It will drive every journalist at any paper of merit insane by interacting with the insane billionaires. Nearly every journalist who uses twitter enough will develop delusions of grandeur that their brand of psychopathy is the solution to the nation's woes. Since their bosses have also been driven insane via twitter, it's the kind of writing that gets published. This writing will take the insane delusions of the insane billionaires at face value. It will go along with conspiracy and never beg any question that actually needs answering.
It's truly a unique and addicting environment.
Pretty much all of my Twitter (and Twitter clones) interactions are involuntary when they show up on news articles or other media.
If the law would force them to say "Do you want Larry Ellison to get richer by looking through your webcam? [Yes] [No]" it would be a good law.
