>even a tiny probability that it might be a threat has to be paid attention
What if it had been named "Teddy Ruxpin is my friend", but the pilot doesn't know whether that's a secret code for "I'm going to release aerosol sarin nerve gas on the plane"?
Should he react to all messages as if they are threats, because no matter how small the risk is, more than zero is too much?
If you can't know whether something is a threat or not, the only reasonable response is to treat it as a non-threat. Anything else leads to absurd outcomes that make it harder to protect from real threats.

No. But he should treat messages that are blatantly intended to provoke others as such. If someone on the flight is going out of their way to cause trouble, kicking them off is the smart move.

To someone whose primary consideration is safety, like the captain of an aeroplane, your logic is entirely nonsensical.

I'm unable to find any connection between Teddy Ruxpin and sarin gas online, so I don't see why a pilot would make such a connection. Am I missing something?

Have you ever been in a position where you were responsible for the safety of several hundred people?

That not turning that Bluetooth device off when told to was going to end up delaying the flight.
