Musk could accomplish exactly what you’re saying on a blog (just as Bezos did on Medium recently), or through a PR release written or approved by him. There are numerous ways he could communicate more effectively to the public without mainstream media filtering. Why do we act like Twitter is the only way to do this?

Twitter only encourages misunderstanding and posts without thought. The character limit is a big driver of this.

If Musk wants to take his company private then he can do whatever he wants, but there is a different set of rules for CEOs of publicly traded companies for a reason.
