If you don't want your content to be bridged to bluesky without your consent, you shouldn't have to fight with anybody except the admin on your local mastodon instance. You can yell at them all you want. I have fewer judgments about that.
Many people have yelled at the bridge guy telling him to make his tool opt-in by default. He shouldn't have to do that. You can make your own instance opt-out by default. Why is that not a preferable solution?
