"Will Meta enforce content moderation policies on other servers?"

"Just like any Mastodon server, Threads will have their own moderation policies and tools, and just like any Mastodon server, they will be able to choose which content to block on their platform. However, their decisions can only affect their own platform. "

Of course, this is the best one. Typical libertarian individualist approach, no idea of coercion or unpleasant tradeoffs, nor of interdependence.

What if Meta defederates from you until you accept their ToS? What if you don't want to, but have to because all of your friends and family are on Meta? I mean, this is the dynamic they have been rolling with since forever. Why would this be different?

Mastodon.social is for all intents and purposes already unblockable because it is so big, and you will sever so many valuable connections by blocking the instance. This dynamic will only be exacerbated by Threads.
