Would defederating make things worse? I would want to see posts from these users and blocking them would force users to use Meta’s app and in turn more likely for users to switch over and create accounts on their app.
I understand its a big scary corporate business but the fedaverse should be open. Closing off a potential big userbase does not seem to be the smartest move and it opens up the rabithole of instances starting to block each other left and right, ruining the entire point.
Copying this from another comment I made. Defederating would pretty much cut off a lot of potential new users that want to see posts on Threads while also not wanting to have a Meta account and all the issues that come with it. People here need to realize that they are in an echo chamber. Mastodon and Lemmy needs users and content. Cutting a big portion of that would kill it in the long run. There would be nothing to “extinguish” in the first place in their complaints of Embrace, Extend, Extinguish.
