If this is the case, I urge EVERY instance admin across all currently federated apps to blacklist threads.
If threads is allowed to federate with these apps, it will outweigh all contributions to these apps, and when Meta eventually defederates (which they will), the vast majority of the community will be lost.
PLEASE HEED THIS WARNING!
While I appreciate the positivity, we also have to remember that federated networks are in part a direct rebuke of corporate-owned social media in general. They have a lot of reason to try and weasel in for profit – and such weaseling is directly antithetical to the reason all of this exists. So in my view, there is good reason not to blindly accept the Trojan Horse of Meta in this situation.
