> No. Run your own DoH server, point your DoH client to your own DoH server ...

Except when the client ignores what you tell it. Per Paul Vixie:

   google, this is bogus as hell. my dhcp server gives you dns servers to 
   use. please don't make me route and answer 8.8.8.8 just to watch youtube.

   (no, this device i've paid for, will NOT be allowed to send you any 
   information, other than what i personally approve, which will never 
   include DNS traffic. if you don't like that deal, buy it back from me 
   and i'll find some other video appliance that doesn't twist my arm.)

Of course with DoH you can't just do a UDP redirect. With DoT, which uses tcp/953, you can at least block access.

But with DoH, you have just lost control of your network. (Unless block 443 and force everything to go through a (Squid) proxy?)
