I already acknowledged how that does not protect the community itself. Including from potential unethical practices/non-consenting experiments by Threads against users, seeing as how that is an established practice of the parent company.

If Threads is federated with Lemmy.World, could they not carry out actions that would in-turn affect users from this instance?

For example, say they manipulate the hot posts on Threads to be depressing content to experiment on moods (again). Would that manipulated feed not affect users of this instance with the federated content?

Or what about how FB and Instagram promoted misinformation many times over, and which is a current problem on Threads? How is this different than defederating from Exploding Heads?

It seems wild to me to federate with a notorious bad actor like Meta/Threads. It’s so clearly in opposition to cultivating a healthy fediverse IMO. The immediate payoff is more users in the Fediverse, but I think it will be a mistake in the long run.

People advocating for trusting Meta/Threads this time after their history is like believing that touching a hot stove won’t burn me this time.
