Yes. If you could transport information faster than the speed of light, it’s easy to find examples that break causality, where an observer sees a message arrive before he sees it being sent.

It’s argue that that would be breaking our ability to properly interpret causality, not that causality itself breaks. Things still occur in the order they happen regardless of what order we see them happen from different perspectives.

No, not if the observer can see the message arrive first, and immediately send a faster than light signal to the sender that turns off their transmitter, preventing the sending of their message.

If they see the message arrive, it has already been sent (and received). Not seeing it get sent yet doesn’t mean it hasn’t happened yet. You’re not accounting for the frame of reference translation involved. Some of the information in your example has travel time. None of that information starts traveling before the things that created that information occurred, though.

I’m sorry, but all of special relativity disagrees with you.
