...which is the exact opposite of what these platforms, as businesses, were designed to do: maximally amplify and disperse the most "clickable" information - which is the one understandable to everyone (dumb) and appealing to people's instincts (authoritarian, because we are herd animals).

given the power these platforms have, i highly doubt this attempt to regulate their business in a clearly negative way to them, can be successful. they are so powerful, even CCP is afraid of them, starting a crackdown on social media in China.
