More competition and greater accountability (you can't really measure conversion rates for TV ads) means advertising services have to be more effective. Showing people ads for things they actually want is the best way to go about that.
Facebook et al do not owe you ANYTHING. The anti-tracking crowd seems to feel it's entitled to services while providing nothing of value in exchange. That's not how the market works. Your attention alone isn't worth much if a website can't show you ads you're likely to act on.
I don't like it either, which is why I run AdBlock and pay for things that are valuable to me - NYTimes, New Yorker, local paper, and phone (nothing sensitive on GMail so I don't care). As the saying goes, you're not the customer, you're the product.
