You're missing the point.
Blocking a popup prevents a separate page from even being delivered

How can there be any derivative works issue when the blocked popup page is not even being delivered?

There is a difference between the user refusing to see something at all (i.e., popup blocking) vs. the user allowing software to actually re-write the copyrighted content they do see (i.e., AutoLink). And in the former, no bandwidth is costing the web-site, whereas the latter steals the web-site's bandwidth.
