> it'd block YouTube ads and similar on my Smart TV and mobile devices - it didn't

thats because you need to tell DHCP to use the pihole's address as primary DNS

I did. I should point out I work for an ISP, so my day job is managing proxy farms, DNS, and so on. It just didn't seem to stop ads on the Smart TV with any variation of whitelist/blacklist.

Even if you do that, there’s some devices (Chromecast, Google Home) that have Google’s DNS hardcoded and ignores the servers passed by DHCP.

What happens if you set your firewall to block 8.8.8.8 and 8.8.4.4?

You can use an iptables rule on your router to rewrite the address to your custom server, which I have done specifically because Google devices were ignoring DHCP.

Something like...

iptables -t nat -A OUTPUT -p udp --dport 53 -j DNAT --to x.x.x.x:53

...should work, and repeat for tcp

It bricks the device. See these previous discussions.

This is terrible. What prevents them from doing the same to android phones and tablets?

That still doesn't fix the ad situation. There's still stuff that goes on at the JS level that a browser ad blocker catches, but a DNS blocker won't. That's been my experience after installing Pihole on the home network.
