I actually prefer personalized (targeted) ads, as long as it is a company I trust with my data. And they generate more revenue so they would need fewer ads.
I realize people will argue that they don't generate more revenue, but if that were true then how has this whole industry developed around them?
By tossing out personalized ads we are throwing out the baby with the bathwater.
And there are so many truly nasty things going on on the Internet, how has killing personalized ads become one of the defining battles of our times? Heck, even just looking at my ISP the list of nasty things they are doing without much push back or notice is scary.
