I don’t run VPNs at the router level. The speed and latency hit, plus the spambot triggers aren’t worth it for me. This is purely a non-privacy minded preference, mind you, and I’m totally not an expert.
You bring up a good point though. Regardless of what’s running upstream, if my device is running private relay, it all gets bypassed. So I have to disable private relay.
My preference is to run nextdns over DoH, AdGuard locally on iOS + Stop the Madness, and a VPN when I’m feeling sheepish.
I don’t even want to imagine the environmental studies and hurdles they’ll have to jump through to artificially alter an areas day/night cycle. There’s a laundry list of environmental concerns that I’m sure any homeowner or eco-activist worth their salt would jump on. Not to mention glare and impacts to air traffic, on and on.
Would make my solar panels pretty darn effective though. Would probably be great for SAD in winter too. Clever idea. Not sure I can get behind it though.
