Isn't the general message that distrust is growing? Maybe there is important feedback here.
Let's assume webmaster central is a positive intention. On the other hand you can't give away to much information. That information vaccum will lead to speculation.
Somehow the problem is that communication needs equal empirical background, which doesn't exist. Google employees know more than we do.
Wouldn't that mean that communication is doomed even with good intentions on both sides?
I can only see this going into a wrong direction with Google employees that try being increasingly alienated and reverse.
If I would have told my supervisor in my PhD that I just collected data to not use it, he would have freaked. Data gets collected to be used.
The problem is unsolvable in my opinion. You (as a company!) know everyting about us, we are just guessing. That's a recipe for disaster and frustration on both sides.
