@sordid I personally think it's incredibly important for the future of the fediverse/social web to be truly open by default. This means not building walls for fear or profit.
I know this is a bit controversial but I think we should be more focused on tearing down walls rather than building new ones. And I think this principle should be upheld for Threads given that @potus and many others are federating from there as we speak. This is a huge win for the open social web.
Having said that, we will certainly have to continually reinforce protections and moderation in the fediverse because there will be plenty of bad actors and users. Just like any other thriving social network, there will be lots of threat vectors that we will need to address as we grow.
Fortunately I think there are a number of smart, surgical ways of doing this without having to wall off 200 million users from the fediverse, most of whom are well intentioned and will be a hugely positive addition to the vision so many here have been working toward for years.
