DNS blockers are nuclear option

Sometimes they are useful but in most cases you need more flexible solution

Why should it? Most ads are toxic. Even if the site is well-intended and doesn't put too many of them, the few ads are still going to track you and disregard your privacy.

This is tech limitation

If site has ads served from main domain you can't block them

You can block ads with some static files on subdomains/domains, and this drastically change content (like how is image sites looks like without images?)

So, using DNS filtering for big ads providers is OK

For small and smart ads providers will not work

And I mean ads and tracking the same thing. While you can block all kind of "analytics", at the same time you can't block web-server logs with your IP (cookies, etc)

That's why I use it in conjunction with Firefox (set to the strictest anti-tracking level) and uBlock Origin

And this is right way to use it
