I'm a very happy paying customer of NextDNS (https://nextdns.io) which blocks known adware and tracking hosts across all mobile and desktop platforms.

Which does absolutely nothing if your device or the app in question is permitted or otherwise not prevented from making DNS-over-HTTPS (or, less commonly because of its discrete port, DNS-over-TLS) queries.

Don't all the ad-blocking DNS providers also support DNS-over-HTTPS now as well? I use it with AdGuard Home, and I saw PiHole supports it as well.

Facebook hard-code IP addresses when their domains are blocked. I found this out while using NextDNS alongside that logging functionality that iPhones have. It’s insane the lengths that they go to.

It's not insane at all. It is the entirety of their business model, so it makes sense that they will do everything possible to keep that sweet surveillance cash flowing.

Sounds like an anti-censorship or a generic connectivity robustness feature [0]? WhatsApp and Instagram do this, too.

One more reason I don’t use Facebook and will never install their app on my phone.
