Take in airplane rules

I will not use TOR to defend Alec Baldwin but would like to shine some light on a practice which airlines participate in which makes absolutely no sense. Baldwin got kicked off a flight for refusing to out away his smartphone so he can continue playing Words with Friends which I get because that game is incredibly annoying.
I get airlines need rules and need ge ability to enforce them in this age but honestly I have asked this question before: Airlines say that phones must be turned off when the door is closed prior to pulling away from the gate yet you are allowed to use your phone the second the wheels touch the ground upon landing. I just ask for consistency
In both cases the door is closed, in both cases you could e interfering with radar and yet in one of the cases you are getting kicked off a flight while the other you are applauded.
