I mean, the threat was, but the fediverse reacted and most instances (that I know of) just defederated preemptively.

This blog post seems to point and laugh that "see, we hadn't needed to put out that fire, it's fully extinguished now". Well, yes. Because we put it out.

But there is also the point that Meta users and Fedizens didn't really have any interest in federating with each other. In that respect, the outcome was fully foreseeable, and Meta's attempt pure signal value for the corporation.
