Yes. Mark Zuckerberg is a yellow journalist. This is crucial information to understand. Mark Zuckerberg is not Facebook though, and Facebook is a valuable information resource.
Twitter on the other hand is a mud wrestling free-for-all. Twitter should just ban political accounts. More specifically, Twitter should be reserved for journalists. Bloggers. People who are reporting the news, which is theoretically anyone who has a cell phone and is present at a newsworthy event. People who hold political office should simply not be allowed to have a Twitter account. They could have a managed Twitter presence without one anyway.
Facebook should be tasked with verifying ad content. Just like any other intermediary, they should be worried about their own status and reputation enough to make sure that what happens on their platform reflects well on their reputation. If they won’t do their due diligence, then the corporation should be nationalized and/or closely regulated. They have billions to spend. They should spend it on maintaining their reputation. Otherwise, why are they allowed to exist in the first place, and why are we spending so much time on their platform?
…But breaking up a communications network is a joke. Ma Bell was broken up and that did permanently cut the cost of long distance calling. But the network reassembled itself because that is the nature of a communications network, that everyone be on the network somewhere or somehow.
You break up Twitter and then what? We already have that, it’s called Mastodon. The behavior will just go there and we still have the problem of spreading misinformation. You break up Facebook and then what? We already have dozens of variations of alternative Facebooks; and again, the behavior will just go there and still be spread. The behavior is there already, and is being spread there in a more limited capacity.
What is needed is regulation. Law. Law that holds these platforms accountable for the misdeeds conducted with their information services. Otherwise the behavior of the users will just get transferred to another platform. Fix the problem, not make it move somewhere else. Make the platforms police their own user base, or create a regulating entity that does it for them. Fine them when they fail to protect the weak from the strong. It’s either that or we let Western civilization spiral down the drain. Pick one.
