I can't stand this precious style of writing. I wish it were less ubiquitous. I think what upsets me about it is that it's disingenuous. When it registers as "cute and charming", it flies over the reader's head and doesn't encourage them to evaluate for themselves whether something like an IRB (or whatever) should exist. If it comes across as disingenuous---or if the reader doesn't feel like the "very mean very bad people" are "very mean" or "very bad"---then the reader is put in the position of feeling like they're going to rain on someone's parade if they disagree. Basically, it's a rhetorical tactic used to forestall argument or discussion about something the writer finds distasteful. I find myself unwilling to read an article if it opens this way because I don't feel comfortable trusting anything the writer says since they've already opened their piece with a piece of rhetoric which is essentially dishonest.
