You mean redirecting on your router? How should google stop you from doing that? And why would you redirect to cloudflare lol

I set up my firewall to block all outgoing traffic to ports 53 and 853 (except for the upstream traffic from my pihole). I suppose DoH could still sneak through though.

FYI for those using DNS-based adblocking: I discovered that my AndroidTV box asks 8.8.8.8 when my local DNS server blocks a request.

The fact that it sold out proves that no one wants it?

On Calyx you can choose the time (between 1h and 72h)

I feel your point regarding the WiFi devices and that they shouldn’t be recommended to casual users. But if you just set up an isolated VLAN with its own SSID and use e.g. homeassistant running locally to orchestrate them, then what’s the harm? If your goal is privacy, you need some kind of local “hub” anyway, and to me it makes way more sense to be able to place that machine anywhere, regardless of e.g. bluetooth reception to your smart home devices (since that is taken care of via the additional SSID on your WAPs).
