Surely if these people were genuine they would organise a spokesman, say someone who is a retired ATC or CASA employee.
Unless that retiree has other aviation affiliations then by definition they no longer work in the industry, so why would/should such a spokesperson subject themselves to being attacked from you and the powers-that-are, and why should the powers-that-are take more notice of them over voters who tell the apparatchiks the reality of their decisions.
Nup, I don't believe that is the reason these cowards hide their names - more about not being really confident about their belief's.
You
really really cannot comprehend the fact that most people in the aviation sector (nay, world), simply
do not have the financial resources to do what they want and when they want., unlike yourself.
Just because someone dares to disagree with you that is
not a sufficient reason to brand them cowards.
