Just for the sake of argument, say the O/S has increased and the TA is ungagged....
What if, by necessity and because it would spoil deals and ruin plans, Keith is unable to give an adequate explanation for the increase in the O/S.... not because anything's wrong, but simply because for the sake of the company he can't give the true explanation without sacrificing a big chunk of the company's immediate future?
How is that a good thing?
You criticize the CEO saying he's only interested in silencing "yingyangs"... yet that's what you're asking him to do with the TA... ungag the TA to silence the "yingyangs" who keep complaining about it. What's the difference?
Six of one yingyang and a half dozen of the other if you ask me. Either one would be only to silence the yingyangs, and I don't think doing so if it's sacrificing the progress of the company is a good idea.
Now, if ungagging the TA advances the goals and future of the company, then by all means... open it up!
I just don't find your reasons to be any more compelling than those you attempt to counter.
