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.

Time Warner Cable used to do it. I haven't checked since they became Spectrum.

There were certainly a number of ISPs in the UK that tested ways to inject ads in content in the 2000s, there was quite a hoo-hah about it in some forums. That was usually by modifying HTML content in transit via transparent proxies though, not DNS poisoning, but it shows that the intent exist{ed|s}. This is one of the reasons that HTTPS-everywhere is a good idea even if you aren't concerned about snooping in general.

An example I remember is when Virgin Media replaced any DNS queries returning NXDOMAIN with their own "search page" plastered with ads.

Ah, yes, I forgot the NXDOMAIN hijacking.

I was thinking about interfering with existing sites.

Some mobile phone network carriers would inject certain PII (such as your mobile number) into HTTP request headers sent to ad networks. I'm sure they still do it, but by requiring the site to have some extra request to be made instea.

Some carriers also passed info in these headers to be used to make billing calls to the Telco, such as subscribing to premium services with minimal (if any) consent from the user.

I got stung by this years ago. An ad for mobile ringtones showed up on some news site I visited on my phone, I scrolled past without clicking. Next minute I get a text telling me I've subscribed signed up to a (iirc) $25/month ringtone plan and that it'd show up on my phone bill. It took an hour on the phone to my carrier to block the charges and get a refund. The ringtone company kept messaging me for a year that I needed to contact them and "fix" the issue.

Insanity that people used to pay more for goofy little midi files than they do now for Netflix.

Deutsche Telekom (largest ISP in Germany) did this, not sure if they still do or were ordered to stop by court yet
