You remove your mask = you are smoking onboard basically.
The airline should write down in the conditions of air travel (and make sure it is also written all over the place on the website / e-ticket receipt) that it is compulsory to wear a company provided mask anytime onboard the aircraft. Now that brings a couple of problems : 1) what about young children and/or adults with respiratory diseases (such as asthma) whom most likely won't be able to wear a mask for the whole duration of the flight ? 2) It is going to work for short-medium range flights (up to 3 hours I would guess) but what about longer flights ? You can't wear a mask for 15 hours on a long haul flight.
And what happens in the case of a decompression. Not sure face masks have been trialed with O2 masks. You'd have to be very quick getting your face mask off and your O2 one on.
