Democracy doesn't work when centralized powers build tools like TikTok or Facebook to influence people's thoughts with bias and other psychological hacks.
If it were me, I would ban all social media platforms larger than 100,000, and create task forces to reign in on predatory marketing and social media collusion.
People just can't be trusted to see how they are constantly being manipulated by companies with deep pockets and foreign governments. Children and adults alike. It's not people's fault either.
Either that or we need a widespread social repudiation of these platforms, a wake up to the fact that our minds are constantly being poisoned, like Tobacco was reigned in.
