It’s not bait. I don’t think the OP that I responded to was speaking about the mechanics of introducing these populations to the Internet (they’re welcome to correct me) but that they shouldn’t be introduced to such things or that the introduction would be tantamount to exploitation of some sort.

I read it more as that a remote highlands PNG villager is not "innoculated" against the concept of, and is not aware of the methodologies that will be used by odd foreigners who have a well thought out plan to convert people to their specific ideology.

Like, if you're out shopping and some person starts up a weirdly friendly conversation with you that leads to a MLM sales pitch, you already know that's a thing which exists and why you're almost certainly not interested in participating even before the pitch arrives.
