Ask HN: Do you have experience in/knowledge of online pro-corporate propaganda?

Hi HN, we all know state propaganda is rife online in this day and age, and well documented both by institutions like Columbia uni and Oxford, and training/workplace videos of bot farms and office workers on youtube.

What I don't see often documented, but I think is equally prevalent, is corporate online disinformation/misinformation efforts. These companies often have much higher gdps than nation states, and their efforts seem more discreet, at least in the media.

Would greatly appreciate anything you have :)
