That’s all on Twitter really. Twitter shot themselves in their one remaining good foot just as Threads was releasing, Meta couldn’t have paid for better timing.
All Twitter had to do to make Threads a pretty ineffectual launch was…nothing. They couldn’t manage that though.
Mods went basically hands off, the only things they would moderate are things that broke site-wide rules like child pornography. Anything else at all was fair game. It was a pretty good view of what unmoderated reddit would look like.
After the usual threats, mods didn’t budge so were removed by admins I believe. Last I heard the place was still an unmoderated glorious trash fire.
