Same can be done with Pi-hole. Yes it isn’t ootb, but it is easy to do.
There are still challenges with doh and isp packet scanning. Even without clear text dns, your isp still knows where you go, if not from the lookups. They still inspect traffic and destinations and can make very detailed inferences, even without https inspection on DoH or other packets.
Pihole is fully for free. AdH seems to be the same for now, but it is a company running it, they want to make money. I would be a bit worried about this.
This also doesn’t stop devices from doing their own dns over https. Adguard home and pihole will try to block the DoH locators (canaries) but can’t actually stop a tv from connecting to a known ip if it wants to.
Don’t get me wrong. I highly recommend something, and adguard home is nice, but I’m not convinced by its the right long term solution nor does either solution provide the sum total.
Code yes, but the information, lists, and capabilities beyond that no.
I do think it’s a low risk, but it is not zero.
They could also do some nefarious stuff if they get bought out.
Don’t get me wrong I hope they last and I’m just plain wrong, but pihole works great and is a bit more pure.
About ui/ux, you are one hundred percent right. People want and demand simple. Single click install and setup is what is really needed and pihole loses resoundingly in that, especially if combined with encrypted dns request forwarding.
