Not me. I work in the ad technology industry. I actually like my job. It's not like you'll be hurting the ad technology industry much, but it will mean your favorite websites (including Slashdot!) will have less income due to lower average value of impressions (a generic non-targeted impression is worth a lot less to an advertiser than a targeted impression). The ad tech companies themselves charge the same to their clients (the ad agencies for buy-side and the online publishers for the sell side) regardless of if the impression is targeted.
