The best way to fight back is to not play the game at all. AI slop has completely ruined the internet, it's not going to get better. It was already on a massive downard trend pre-AI and generative AI has only accelerated the decline by 100x. It's only going to get worse from here.

It's not perfect but the internet feels slightly better when AI garbage is not constantly being shoved in my face 24/7.
I want to go one step further -> I want to hide widgets, but I also want to intercept the request it would have made and replace the payload with garbled nonsense. Similar to how Ad Nauseam will hide ads but it also clicks every single one to poison the data collection.
And for this reason alone you will pry Firefox from my cold, dead hands.
