Sure, it's possible the serving was not done correctly. Even in that case, this does not imply, as you have claimed, that this is "just needless YouTube drama" (emphasis mine). There is clearly a lot going on beyond the obvious flashy setting which is chosen for the presentation.

Arguably, no attention would have come to this matter if not for such presentation, and the perpetrators would have just gotten away with it easily, so it is in fact understandable that things were done in such a way.

Yet you choose to ignore the way more significant issues from B&M's side and focus only on the choices of dramatization of the events, which, if a problem at all, are only marginal in comparison. While further trying to use that a way to try to in fact discredit the more relevant issue.

I feel like I once heard a great word/phrase for this thing where people attack the "civility" of the messenger instead of the actual injustice being reported on, but I can't remember what it was now. It came up a lot during black lives matter protests.

It's called "Tone policing"
