Does that work anymore with DNS over HTTPS? I think the real leak is that until we get Encrypted Client Hello your HTTPS connections expose the domain in plaintext so DNS is kind of a moot point.
And it's hell for the security minded people. Before I could do DNAT on my router to redirect everything to my Pi-Hole, even the Google Mini that staunchly ignored the handed out DNS, but used 8.8.8.8.
But soon they'll start using DoH and I can't do anything anymore at all.
I believe IMDb on iOS already uses DoH.
