We published a post on this shortly after the missed target, in fact, maybe it was missed.
As it says there, we aren’t estimating out loud any more. As you say it’s just a source of frustration, so we’d rather just buckle down and get it done. Keith also specifically responded to this identical complaint that you lodged, here.
As to the rest, it might be best to take that to our feedback channel, if you have a complaint with any of us. Normally I’d not have a problem with it, but inside of a thread that is a dry tinder like this, where I’ve had to repeatedly ask people to lay off of the flame prose, it is not bound to be very productive.
