To be hair Musk posted much more internal information in a screenshot lately. The question isn't really is it incredibly useful, but is there anything that might be a breach of the employment agreements. To this I don't know, but it is still an area where employees should be careful. I personally would never write anything about my employer on a personal blog.

Who's going to compete with Twitter? It's a company worth billions, and to execute the caches and automatic fallover in the rival company with billions of users it would take billions.
