Take a step back. You yourself describe it as a joke. Are you really saying that the quality of the joke ("awful") should result in the origin of the joke (a kid, even!) should be banned from a major air carrier for 10 years? Does this really seem like a proportional response?
And this doesn't even begin to consider another possibility: the device was named what it was named in a completely different setting, and the owner just forgot about it. That makes it not even a joke, just forgetfulness.
Was any of this a good idea? No, probably not, but people need to calm down.
I can understand the safety concern - and I think the decision to turn around was ultimately the right call. Especially given that they had called for people turning off BT for some time.
The fact that the device was not turned off suggests to me that the owner did not know they were the cause of this. If they had done this by intent and were set on going through with it even after the turnaround was initiated, they would have also had the sense to drop the device into some other seat or leave it in the lavatory...
If it turns out they did this with full intent, there should be some _appropriate_ consequence
Sure, if evidence is uncovered of the guy say telling his friends "haha, I'm gonna make them turn the plane around", I can get behind the baying for consequences.
We're nowhere near that. There's plenty of non-nefarious ways this could all have come about, and people need to put down their pitchforks.
I don't, and I think it fits what Bruce Schneier called "Cover Your Ass" security (he was referring to the equally stupid https://en.wikipedia.org/wiki/2007_Boston_Mooninite_panic)
It sounds like a fantastic DDoS opportunity, you could shut down an entire nation's aviation just by putting a few tiny bluetooth transmitters in places that air passengers might accidentally pick them up. The attack relies entirely on the overreaction to non-threats by ignorant buffoons in positions of authority.
Personally, I think the airline and its policies should be publicly ridiculed. If we don't punish the airline for doing this, and make unequivocably clear that it did the wrong thing, that its "what ifs" are meaningless and bluetooth/wifi channel names are not a security threat, then this nonsense will just continue.
My wife would have probably freaked out if she saw a wifi network named "bomb" on the plane. So as an airline security officer I'd totally ban this kind of behaviour.
