Well BA certainly
do have the sort of clause aterpster has mentioned.
Take a look at ba.com, General Conditions of Carriage, it comes up in section 7 ( "Our right to refuse to carry you or ban you from travel")
7a8) If you have not obeyed the instructions of our ground staff or a member of the crew of the aircraft relating to safety or security.
and again in section 11 about behaviour onboard a BA flight:
11a) Unacceptable behaviour
If, while
you are on board the aircraft,
we reasonably believe that
youhave:
- put the aircraft, or any person in it, in danger
- deliberately interfered with the crew in carrying out their duties
- failed to obey the instructions of the crew relating to safety or security
.............
There then follows several other "no no's," such as being drunk on board, then the list of sanctions, up to and including handing over to local authorities on arrival...

I'll put money on many/most/all (?) other airlines having similar clauses ticked away in their Conditions of Carriage, I suspect some people who "know their rights" might be in for a rude awakening if they insist pushing the boundaries, especially if they decide to turn doing so into some form of performance....TBH I really really don't see the difficulty in quietly appearing to pay attention to a yet another safety briefing....
