I think if a certain contexts encourages a certain behavior, that's not something essential to humanity. if a group of fur trappers has to resort to eating Jean-Luc because they're trapped in a mountain pass during a blizzard and starving, I wouldn't say that cannibalism is "human nature". I similarly, wouldn't say that the behavior engendered by modern social media is so essential as to be labeled part of our nature ( maybe we could say the adaptability of human behavior to environment and circumstance is inherent, but that's a different kettle of fish).
I don't find this analogy enlightening. Only a few people are ever trapped in a mountain pass during a blizzard and starving, so of course it doesn't tell us much about humanity.
Whereas millions of people participate in online forums every single day, and not because they're desperate, in danger of death or the like.
