You are right. In principle, the AT protocol is designed for federation. But at the moment, there is only one Bluesky instance that everyone is signing up on. This makes it effectively centralized like Twitter. It is mind-boggling that people are ignoring Mastodon for this.
You are confusing taking a class with actually having ethics. No amount of attending a lecture about ethics will convince you if you do not, as a basic premise agree with the ethical principle that loss of life is a bad thing. And to be very clear, ethical principles are subjective. There is no objectively right or wrong thing as far nature is concerned.
But…does it sync?
