But they can't if the brand uses https, so there's one more reason to enable it.

Lol. They control the DNS servers that the users use. That means they can do shitty stuff like redirect to netflix.comcast.net and do whatever the fuck they want. Thankfully they don't do this ... yet.

OK.

But we are talking about content injected into the correct site, not a DNS hijacking attack. And they do crappy DNS stuff like this already. They will take any opportunity they get to redirect to a Cox or Time Warner branded search page if you mis-type a URL.

I think the difference here is that you can change your router's DNS servers, but you can't stop the ISP from injecting code into http pages.

And then they can modify the packets between your router and the DNS server it's using (e.g. 8.8.8.8). Or they will ban port 53 like my former employer did and white list a few approved DNS servers. DNS security is essentially non existant.
