As I was puzzling through that, I landed on what I think is a core issue. People do not feel that the tools necessary to protect themselves *are in their hands*. They're still operating as if they have to ask other people to do the right thing. (Or yell at them as the case may be). Is that a failure of the way mastodon is set up? Have we not gone far enough with "you get to decide how your presence on the internet works"?
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?
