On the other hand, you can only argue about the estimate if there is even a channel to argue about it. I have seen several cases of (1) people being told about a deadline through various proxies, so there was no point in time where they could even question the imposed deadline, (2) people not being told about the deadline at all until it was missed, so they could not argue against it, (3) people not being told about the task that has a deadline until after that deadline was missed.
