I'm also not opposed to targeting in principle, and in fact I'd love to reach an end state where a company - whether you call it an ad company or otherwise - does 98% of my shopping for me. But I feel like we're in an uncanny valley in which adtechs are hoovering up more data than they'd even need to do that, but with no incentive to push consumers toward products we'll actually be happy with. Facebook is probably better off if your new jeans wear out in a few months, and Amazon can't even be trusted to reliably ship you the products they think they're shipping you, let alone vouch for their quality.
