Google ads (like most ads) are hosted by websites that intentionally put them there; install an adblocker. Google doesn't MITM sites; ISPs and malicious networks do. ISPs are also known to surveil traffic on their networks. I'm not disputing that Google ads and tracking, like all other ads and tracking, should be blocked. Run a browser you trust, and run an adblocker. But the widespread use of unencrypted DNS is a problem that needs fixing. And DoH provides the most viable solution for that problem, by running DNS over an ordinary HTTPS connection.
