I highly recommend Isaacson's Biography of Musk. It contains quite a bit about Musk's version of free speech and his vision including such things as community notes.

For my part, I had started talking through intermediaries with Twitter about what is now the Internet Court of Truth or TruthCourt.net. CN is a 'chinese copy' of that. But CN is pretty wrong headed in ways you mention and others. Some of the notions you develop are also wrong headed. A good book to read is by Bowyer Bell. Here is a review of his book and a similar one by a living professor in Washington State.

With Truth Court we have found that if you actually experience it, you like it. But, like trying to explain what it is like to ride a horse, you really do have to experience it to understand it. I had similar experiences with CN and found the problems you mentioned that are pretty bad problems. Curating process is worse than curating content. TruthCourt doesn't curate anything. It lets anybody who suspects something in the media is a lie or who wonders why people think what he thinks is true, isn't, get a few other people in a short time to dissect it. It covers the case where your doubts or the doubts of others can be checked quickly and transparently. And it works.

It does not, however, curate either process or content. It leaves that to people who are the experts at that.
