The contemporary usage of "cargo cult" is synonymous with "bandwagon effect."

First, you can call it out as wrong. But I have never seen such "enlightenment campaigns" succeed. Nobody likes smartasses that write "accctttuuuaaalllyy" articles.

Second, "cargo cult" is a useful term even if not rooted in reality. That's also why it spread and persists. It fills a void that, for whatever reason, "bandwagon effect" never filled.

Third, speak for yourself. The zeitgeist moved on from moralistic language lecturing. The more you associate it with virtue signaling, the less will people adopt it nowadays.
