If you want to see how #Meta's bias towards boosting emotive content regardless of harm is _already_ reflected in how they build Threads, this post is a good example (CW: transphobic comments in screenshot).
A transphobic post is used to _advertise_ #Threads to an Instagram user.
It looks like that account has been deleted. But we'll see more examples, and I hope that underscores why many here want to, at the very least, be cautious in how we interact with Threads.
