https://nitter.net/TechEmails/status/1575588277700026368 has the purported conversation between Dorsey and Musk from March about how Twitter should become "an open source protocol, funded by a foundation of sorts that doesn't own the protocol, only advances it". Purportedly the thread was made evidence in the Twitter v. Musk lawsuit.

If that's the plan, firing most of Twitter's employees does seem like a good first step.
