I am in perfect control of my reading experience when I have a magazine in my hand. I can either look at the ads or skip them, or I can just glance at one and decide which way to go.

This is in contrast to web where I'll have to start by choosing a set of ad-blocking plugins to allow me back even some of that control even before I've read a single article online.

I don't particularly even care that much about ad networks tracking me, that's more like a philosophical / ethical question that is invisible in the daily life. Web ads aren't bad because of tracking, it's just that they're mostly bad ads.
