Virtually every website on the World Wide Web will track and record IP addresses as visitors click through the site's page. There are plenty of adblockers to prevent sites from using ads to target you. You seem to be more upset at Google than the sites you visit that choose to use them as a source of revenue. You also can't shop on Amazon without being tracked and solicited to based on your shopping habits or sign up for any discounts at most grocery stores.

Makes perfect sense to me since Google earns most of their revenue from privacy invasion. Their entire business model depends on it. No one is more insidious, pervasive and widespread.
You really are just making claims without any evidence. If you have evidence that no one is more insidious, pervasive and widespread please prove it. Otherwise, I can only assume you are just speaking based on feelings.
If you actually read the study, you'd see with ad blocking enabled that Google was the least pervasive, widespread and insidious. If anything, this study shows that although that Google may be the most widespread, again thanks to the sites that you're visiting without an adblocker that you refuse to hold accountable, that they are the least invasive and insidious.
