It’s interesting that Mastodon instances are trending in the opposite direction of Lemmy instances. Most are staying federated with Threads. I wonder if that’s simply indicative of the strong anti-corporate culture on Lemmy, or if there’s more to it.
That FediDB stats page is confusing. It isn’t clear whether they only count instances that have joined Fedipact, or also include instances that have blocked Threads without joining Fedipact. A quick glance at the list suggests the latter. But in that case, there are a bunch of instances missing from the list.
The list on the Fedipact site is a better source:

As for admins versus users, here on sh.itjust.works we held a vote among our users. The result was overwhelming: 78% of users voted to preemptively block Threads.
