Comcast and/or verizon did it in the 2010s, there was an opt-out in the account dashboard.

It's sort of an absurd question, the prevalence of such things by ISPs was the literal impetus for DoH and DoT.

Last I checked Verizon FIOS still has the opt-out. You have to go into your account preferences and manually disable it because spying is on by default.

This is a good reminder to login and take a look, I wouldn't put it past them to change the setting name and reset the default.

edit: apparently Verizon has zero record of the username I've used for my FIOS account for years (and have saved in my password manager). Their account reset also fails with an error. What a dumpster fire of a company.

Yep, I've been in Verizon online account purgatory for awhile now. They merged my mom's with mine and nothing works to reset or restore online account access for even bill pay. I have to push their payment out via billpay. I really need to move that phone number over to voip, I kept the classic POTS line as a type 1 diabetic I like that it stayed on during both NYC blackouts in 2003 and 2012. But now I'm in a fiber only building and that redundancy is mostly moot.

Thank you for this. Just opted out. They certainly made that page as hard as possible to find. Figuring out how to change my routers DNS server was also made needlessly complex.

You should be NATing outbound 53 to a local resolver that upstreams to DoH/DoT. Relying on such an opt-out is rather optimistic.

		I don't use their resolver at all. Their opt-out was more of an all-encompassing "let us take whatever data we can manage to get" than DNS specifically.
