But yeah, X, LinkedIn, and the rest all feel like the bots and content farmers have taken over.

I believe the pay for engagement incentives make people be as controversial as possible just to earn money. Imagine you are in a low-income nation, you pretend to be from the USA, you could earn a higher daily income by posting engagement bait. It is in your interest to upset as many people as possible and then set up counter bots to argue with your fee earning bots.
