But the internet is mass media.
Billionaires that want to influence people find them in places like Reddit, Facebook, Twitter, TikTok, and yes, 4chan.
The fact that 4chan is a wild west, rules-less zone is why nazis congregate there the most (or used to, Twitter is basically rules-less now), and that's why it was able to operate as a cultural think-tank.
I take it back, I don't think you're defensive, I think you just find the idea of funny green frogs unraveling democracy too embarassing to consider.
