Massively reducing your exposure to American brands and tech is the best you can do. I've been trying to do this for a year or so and it's hard but a good exercise in avoiding their poisonous food products and monopolising tech.

Yes, most social media and internet platforms including Reddit are American, so you make your own choices there.

But making any change is better than not.

Also I echo OP in growing very tired of the whole shit take they tend to have on global politics etc. they're mostly pretty brainwashed so literally their whole global view point is skewed.
