I've expressed few strong opinions about the #Threads issue, specifically, or the defederation issue more broadly, but I think the fact that there are very good arguments for either action is indicative of a systemic problem.
The two positions (simplified):
Anti-defed: "I want to see my friends posts, and I want them to see mine." I want that, too.
Pro-defed: "I never want to see Nazi shit on my feed, and I don't want my followers to see Nazi shit on my threads." Yep, me too.
