The combinatorial explosion mentioned in the above post - it would be bad enough if the requirement for moderators expanded linearly with users, but it actually expands exponentially, more like with interactions.

Plus, Musk tweeted that he's eliminate bots or die trying. If he really means this, it would be a truly great contribution to twitter -- free speech is one thing, but amplified disinformation is another. But, this apparently requires levels of effort beyond all the social media today, especially when it is not just automated bots, but also paid troll farms grinding out disinformation and deliberately undermining communications.
