> The accidental thing nobody noticed is how @Cloudflare is suddenly in the best position now to take over the Web Analytics industry now that adblockers are all blocking JS-level Google Analytics, since Cloudflare can track users on the DNS-level

So once DNS blocking becomes the norm, the power to do evil will switch from Google to Cloudflare.

DNS analytics are pretty much useless for web analytics due to wildcard records, multi layer caching,etc.

Umm....Agree....maybe is worst than google.

In principle this is a good service, but in practice why would one trust a closed source third party if privacy and content blocking is a major concern?

A pfSense machine with pfBlockerNG is open source, fully customizable, and can block at the DNS and IP level.

Since blocking content effectively changes how the web looks, and can occasionally break web sites, I'd rather have full control over the service than to pay someone to configure it for me.

Plus, the BSD camp has yet to let me down. :)

I just started using https://www.nextdns.io/ that offers so much customization and a whitelist
