I seem to recall that the mainland Chinese govt has a similar policy. I'm sure that no citizen of China manages to read outside news or post comments on social media
. Funny how totalitarian organisations and like-minded individuals fear the truth, and fear people discussing that truth. When almost everything they say and believe is false, it is understandable why our managers fear the truth. The management also don't seem to realise that this further attempt at intimidation is just further evidence for the 'thinking pilot' to help him/her make up their minds to leave. As if they need yet ANOTHER reason...
