He specifically agreed to have Tesla legal review all such tweets to make sure he doesn't tweet bad information again, and promptly went and ignored that.
Except by some particularly whiny people looking for an excuse.
TSLA stated five years ago that Musk's twitter is an official source of information regarding the company.
As pointed out many times on this thread, Elon had Tesla designate his personal twitter account as an official source of material company information. Ergo, anything he posts to twitter is potentially subject to SEC reporting requirements.
