I agree with you, Warner. The only way to limit your data feed now, is not to have any (no phone, no online presence at all, cash only transactions).
But I still enjoy imagining screwing up American big data, as much as possible. These supremely selfish billionaires could be doing incredible things to advance humanity, health, peace, culture....
But no: nothing but consumption and greed. I'll consider myself fortunate, if I can see them burn.
