Have you seen or do you remember that classic british comedy tv show "Yes Minister"?
Its often not what said but whats not said thats relevant.
Canberra is a Public Servant dominated city. Many are 2nd or 3rd generation public servants... and proficient in "public servantese talk" i.e. informing others by omission

..so the press cannot attribute directly to you any "leaks"
What has this got to do with undressing co$? A lot. Public Servants are supposedly neutral .. they cannot use their position to cause changes thats suits their own agendas.
However

the "Yes Minister" tactic comes into play here.
There is a buddy network that stretches at different levels throughout many Govt departments. Let us say co$ tries some sort of letter writing campaign, or recruiting tactic that questionable etc .... all it takes is for a few whispers during the after work social club drinks session...and a conversation started within earshot of a senior official whose portfolio covers that area co$ is trying to influence.
I have seen it happen ... the senior official's ears literally stand on end and rotate to catch the conversation. Nothing is said by him. Thats good !

..it means hes thinking it over .. if he did not agree with what was said he would speak out and the conversation killed. "yes minister"... (all bow to his superior status within the ranks...) ..next topic...
Rest assured that within 24 hours the powers higher up are advised. And any co$ propaganda is "assessed" in a legal and fair manner ( usually their letters are "recorded" as is supposed to be done, ... then filed in archives .....99% unread...
There is no reward for this. The only indication that you have been successful is when that senior officer..or one of his delegates.. deliberately stands next to you next after hours drinking session .. and chats with you
The only time I saw a direct acknowledgement was after the education department was alerted to the "drug free ambassadors" using fabricated news items to convince parents and citizens groups to allow a co$ spokeshole* to talk to students and distribute their crap .. and collect students names. I Understand the P & C groups involved were furious to learn that co$ was behind that. ( more enemies, osa

), - Also the minister replied with an assurance that all school drug programs throughout the state would have to be referred to her office in the first instance.

..and thanks for bringing it to their attention.
And the acknowledgement? Well a senior officer sidled up to me with two drinks in hand ... gave me one and commented "You sure write a nice letter - the minister was impressed"
Some of us don't wear masks.... or visibly protest... but we are still anonymous
The venusian traindriver and crew
*( I stole that word "spokeshole" .... its perfect for describing the bunny sent in to try and defend co$

)
co$ deceives no only others, but also its own members.
