I have to regretfully agree. I find this continuing assertion that defederating Meta properties will somehow dramatically harm the Fediverse to be unfounded. I have not yet encountered any convincing argument for how defederating Threads is any kind of suicide whatsoever. We have no Threads now, and seem to be doing quite well.
Is Beehaw still doing fine, yes? They defederated rather harshly, in a far more delicate time than now.
