Google and site owners want to do targeted ads. I'm not sure that users hate targeted ads specifically. I, for one, am not a site owner myself, but I'm sympathetic enough to their need for revenue that I'm OK with targeted ads.
I hate stuff like auto-play video (and am thrilled that Firefox has well and truly conquered that issue) and I'm pissed that many companies sell or leak my data but I'm not looking to reject targeted ads outright.
