... "If I am using a cheap method of accessing the briefing office, why should I directly or indirectly subsidise someone else who elects to use the more expensive access method?"
Because...
1) That person may be in the country and unable to access by any cheap method
2) That person may have already got data the cheap way, and seeks to be compliant by obtaining the latest info after a long drive from home office to the airport
3) Persons (1) and (2) may be less likely to kill you with the benefit of the information.
We are all in it together girls and boys.
