No post has been made that I know of. Mastodon’s CEO laid out his stance in the post below and I would hope Lemmy would follow with them.
Lots of echo chambering going on in here about EEE and Meta profiting off of everything. In reality, they can scrape data like anyone else, the profit from such small communities is negligible, and defederating meta would only hurt those that defederated because way more users than people here think will want to see and manage Threads while also not needing a Threads account to avoid the data hell that it is.

Agree and understand that users don’t want to be flooded with Thread posts. I think until the user is able to block on their own, the main mastodon.social and lemmy should stay federated as most new users go there. If they don’t want to see threads, then they can move to one that defederated. But only until the users have the ability to block threads on their own, then it should be the users choice.
