At the risk of being redundant:
#Meta doesn't care about your posts. Because there is nothing of interest that you could possibly post. You are not interesting for Meta.
#Meta doesn't care about enabling their users to be part of an open network. All they want is hype, marketing and to skim the fallout from Twitter. All they want is their users personal data.
#Meta can never inject ads into your instance or timeline - ergo they are not interested in you.
#Meta cannot even correlate your account to anything in their database.
Meta's release of #Thread is as much of relevance for the Fediverse as a Biden farting in his chair.
