does landing a plane early due to a bomb threat seem reasonable? either there is a bomb, in which case landing early won't help, or there isn't, in which case landing early won't help

Certainly telling them to turn off bluetooth will not have any positive effect, if there was a bomb I presume it would only have a negative effect.

But some people are really dumb when it comes to having common sense with respect to tech (or non-tech too, hehe).
