I believe that has a lot to do with how the experiences are actually different. Advertising are a lot more agressive, significantly more present and rely on data gathered from brokers that are meaningfully more insightful. Just look at the TV ad culture: ads for drugs that are incredibly manipulative, political ads that somehow are worst — and add targeting. The ads I see Americans friends share are terrifying to me. Show-offs are also probably a problem, too; more so that there are less social expectation to peg them down a notch in the US. I absolutely you can make Facebook work for you, but that requires to give it negative feedback (blocking or hiding people, hiding ads) and people have a strong aversion to this, on both sides of the Atlantic -- including data scientists who should know better about training models with balanced feedback.
