I get why World and many others defederated from Burggit. Obviously it has questionable content which is not great to have stored on big servers for legal reasons.
But look at Threads, owned by a company which steals data and causes harm to anyone in any possible way. If you don’t see their actions questionable as well and don’t see how they are parasites trying to leech on the fediverse and suck everything away then there was no point in defederating from any questionable instances.
You don’t have to qualify your opinion that Threads should be defederated by bringing up the lolicon instance. They are two completely separate instances and the questions to defederate from either are completely separate.
Burggit, Exploding-Heads, and Threads each have their own reasons for defederation (lolicon, nazism, corporate influence) and it doesn’t make any sense to bring up one when discussing the other.
