Piholes don’t actually block the traffic. The ads still make it from google to your home network. Pihole just intercepts them and sends them off to nowhere before they get to any of your devices. So I believe they won’t be affected by this.
That's not true. Pihole voids DNS requests, not the actual HTTP responses. When trying to look up an ad, it tells your devices to look at an unassigned ip address which will then not respond with anything.
DNS response from pihole makes it so your browser doesn’t even make the request to the server providing the AD. A blocked ad via DNS doesn’t make it to your device, and doesn’t even get downloaded from the remote server.
