Facebook is the same way with all of this crap too. I’ve seen more success with the hard way, networking and getting content made about me and distributed in magazines or online blogs from people who get to use my service for free.
Sales aren't some abstract thing that can't be quantified.
Site gets no traffic -> Spend $X on google or facebook pointing traffic to site -> Y Amount of traffic -> $Z amount of sales.
You now know how much revenue $X worth of ads buys you. You also know how much each amount of revenue is worth to you in profit. As long as spending that $X makes profit, you're gonna do it. No matter what crap is mixed in by the ad company.
If something you want is bundled with something you don't want and is priced such that you're willing to buy the thing you want at that price, you don't turn it down. You buy it and ignore the thing you don't want.
Keep the budget low, so you wont bother about it, and use money for anything else than Google Ads.
And its not like i am against Google or something. Actually i have a company that runs Google Ads for clients. So i dont have any hidden interest to criticize Google Ads, contrary. But its the truth and its just something i think everyone should be aware of.
Given this, all of the data collection/tracking/etc. seems like a round-off error in effectiveness, and doesn't seem to be worth the loss of individual privacy.
