There's nothing masterful or careful about it. If it were, no one would notice it. This is as obvious and sloppy as it gets. No different to startup founders paying social media marketing companies $10-20k to promote their slop products all over X and Reddit with their army of AI generated blogs and news sites and social media accounts. This happens on the daily, and it is not a secret - every founder knows it, and most founders use it at some point. So to think this doesn't happen at larger scales with bigger companies is pure naivety.

It has nothing to do with "big-evil-corpo", it happens at all levels. For some reason you're trying to claim that "big-evil-corpo" are the rare exception, which is ridiculous.
