Do you have another expression that I should use to characterize your behaviour in reverting a useful edit instead of correcting the minor newbie flaws? You could have deleted the YOUTube links only. You could have kept the useful material instead of just deleting it ("Hold on to the good" - 1 Thessalonians 5:21). It cost me less than a minute to do this. It cost you more time to unload your "upset" in this discussion space, and cost me time to answer it. So should we really take the time to discuss all this, instead of working on the project? Why bother with my comment? I'm not an admin. Just try to be more careful next time.
