What kind of world do you live in? Actually Google ads tend to be some of the highest ROI for the advertiser and most likely to be beneficial for the user. Vs the pure junk ads that aren't personalized, and just banner ads that have zero relationship to me. Google Ads is the enabler of free internet. I for one am thankful to them. Else you end up paying for NYT, Washinton Post, Information etc -- virtually for any high quality web site (including Search).

Ads. Beneficial to the user.

Most of the time, you need to pick one. Modern advertising is not based on finding the item with the most utility for the user - which means they are aimed at manipulating the user's behaviour in one way or another.
