Hello! Scratch Team here. We made those changes to keep Scratchers safe from bad extensions. Of course, we're not saying they're all bad, but many are. We don't want anyone getting hacked, so we are not allowing the sharing of such extensions. We are sorry that you don't like it, but it's what we must do to make a great online community.
Thanks, The Scratch Team.
