Oh the monetization made it noticeably worse. I've been pretty active in tpot/tech twitter and it practically happened overnight. Posters figured out the best way to get engagement was to write things that are incorrect but plausibly believable to generate controversy.

It became so grating, so many people turned into rage baiters.

And you get to see complete outright racism unchecked. Like comments saying the most vile stuff, like calling something a jewish conspiracy, and they don't even get ratioed. Embarrassing to see it.
