Bots I think is both the harder and existential problem.
Plus, you can look at most biased news sources and see the drama that they selectively cover under the guise of news. "1 person did a bad thing" and "here's another reason why this entire group is conspiring against you" are not uncommon tropes.
OK, but then it's more like blacklisting rather than banning. You're still free to show up and participate, you just can't get access to the biggest audiences.
So then the conversation turns from "why is Twitter blocking my free speech?" to "why is Twitter penalizing my free speech?".
Plus, what's legal speech is a real grey area. Free speech cases constantly go to the Supreme Court because we're talking about a near infinite number of ideas that can be expressed. And intent usually matters. So when Kanye writes his "death con 3" tweet, is it a direct threat to incite violence (not protected), an ambiguous threat that's not actionable (possibly protected), a joke (very likely protected), or as a brand new idea that hasn't been expressed yet (possibly protected)?
At the end of the day, a human has to make a decision. So, we're just swapping Jack's and Parag's vision of content moderation for Elon's, but it'll still be content moderation - perhaps better, perhaps not.
Maybe his tweet should stay up, ambiguous speech isn’t clearly illegal. Illegal speech is much easier to recognize. But Twitter probably wouldn’t want to put that tweet on the trending front page or advertise next to it but he has an audience and can continue to interact with and grow his audience.
Minimal regulation as required by law, no moderation, and maximal participation.
It’s impossible for Elon to accomplish his current vision because it’s not internally consistent. You can’t only moderate what is within the law and make Twitter a more friendly place and make it more attractive to advertisers and grow it to a billion users, and make it the defacto public square and make it the free speech public network and eliminate bots, and make X the everything app and fire 75% of twitter employees.
So while I think Elon Musk will succeed, it’s also interesting to point out the paradoxes and difficulty and in doing so elicit curiosity in how he will accomplish his goal. Conservatives seem to be taking a victory lap today, but it’s one of those things where compromise means no one ends up completely happy.
