Are you calling for public censorship????
We are living in an open and free society here, where it is everybody's irrevocable right to talk about what he thinks, knows, feels or believes! It a constitutional right to speak freely and nobody's economic interests can come before that. PERIOD.
If I happen to know something about an airline or an airport, I have the right to post it, even if that airline or airport doesn't like me posting it before they do.
I suggest you don't get carried away by internal memo's from BAC's (or some airlines') spin doctors who feel the regular obligation to point out the staff of their companies that public forums seriously harm their carefully staged PR shows. Remember they definitely have the right to try to win the harts and minds, but remember our constitution gives you the right to speak your mind and nobody can take that away from you for as long as you haven't personally signed up to some sort of a personal confidenciality contract, although I know some companies at BRU often refer to general company rules and policies in which they impose secrecy and forbid company staff from speeking with the press. It doesn't matter though: these clauses are against the law as they unilaterally limit your constitutional rights, something which they can not do, especially not since they are misusing their position as your employer. 100% illegal! Only YOU can decide to renounce to your rights, so if you haven't signed any contract, you are not bound by any of their rules they try to impose upon you! Don't be intimidated!
