I detest ad-driven models and especially ad-driven social media, but this could actually make the problem worse, unless they can profit by a different means. It takes tons of expensive resources and talent to identify, stop, and prevent information/psychological warfare campaigns like these in a haystack of hundreds of millions to billions of users, especially when your adversaries may be superpowers' world-class intelligence agencies and their affiliates, or dedicated intelligence firms like Cambridge Analytica. It's hard enough for the existing companies. (And yes, I think they're genuinely trying. Or at least I think Twitter is.)
