My thoughts are similar to yours, I don’t think instances should be defederating unless there’s a serious issue with the content of another instance.
Good instances should be winning over people by being better than whatever Facebook’s ad ridden, algorithm driven, instance ends up being.
This article is misleading. If a car crash is bad enough that it damages the frame of a car, it’s going to get totalled anyway. So either way it’s going to go to a junk yard and get slowly parted out.
