In general, I don't mind someone using imperative mood, as it is fairly common among (software) developers. Even though we have fancy tools, we do nothing else than building a large dataset, which brings us in an adjacent category. Nevertheless, I understand that using the imperative mood can sound unfriendly and patronizing, especially for newbies. As "eiskalt-glasklar" has already described, the situation is, two banks that have merged. This includes the main buildings, and a not insignificant number of field offices and ATMs. Accordingly, they've created a brief and distinct description of what needs to be done to mend and incorporate the resulting discrepancy into OSM's dataset. Therefore, I think " HostedDinner"'s comment was slightly unnecessary, but, as I described above, I get the point and I understand it.

What happened afterwards was indubitable out of line and does not belong here. Disagreements, both social and technical, happen perpetually. It is important that we resolve disagreements and differing views constructively in a respecting manner, but not like this.

@eiskalt-glasklar: Frankly, I feel it is a great pity that you haven't felt it necessity to apologize to HostedDinner. Contrary to this, you justify your behavior by referring to the importance of this issue, while also questioning the integrity of the moderation. Sorry, I'm just stunned by this attempt to turn the table. Presently, the topic it is less about whether you should use "must" or "should", more about your behavior towards HostedDinner. Instead of threatening to stop mapping, you should think about apologizing to them.
