Personally, I reckon he/she is a bit stiff. Given the number of passengers observed to be obviously using their mobile device from boarding to 20000ft and 20000ft to disembarkation, I'd suggest the Minister is simply doing what the majority of travellers do. The only difference is the Minister was shown to be in breach of the regs and fined.
Why do we continue to broadcast announcements about mobile device usage and then (usually) completely ignore the abuse of the regulation?
If we aren't going to strictly police the requirement, why continue to make the announcement?
Why are we then surprised when passengers take every personal possession they have with them when the words "evacuate evacuate" are announced?
