tl;dr - we engineers are bad at estimation because we're too optimistic, and then we don't want to be accountable to the estimate given based on limited information.
i think we have phobias for estimates because of management repercussions that only happen when you miss an estimated delivery date, or for organizations that put external dates based on a best-case aggressive engineering estimate. then when the engineering team misses the date, there's a retro (when retros should happen for both good and bad sprints.)
i've never been clear why more organizations don't soft launch features or products, and then pick a marketing/external announcement date.
