Leaked presentation shows Comcast is lobbying US lawmakers against Google and Mozilla's plan to encrypt DNS data, making it harder for ISPs to track users
Motherboard has obtained a leaked presentation internet service providers are using to try and lobby lawmakers against a form of encrypted browsing data.
Context & Ripple Effects
The leak lands mid-fight: House investigators had already asked Google about its plans to bring DNS-over-HTTPS to Chrome, with ISPs warning the protocol blinds them to user lookups (House investigators asked Google about DoH plans). Motherboard obtaining Comcast's actual lawmaker-facing deck turns a technical standards dispute into a documented lobbying campaign.
Mozilla's counter-move came within two weeks, urging Congress to reject what it called an ISP effort using Google as a boogeyman (Mozilla urged Congress to reject the ISP campaign). The arc resolves oddly in Comcast's favor: eight months later it became the first ISP inside Firefox's Trusted Recursive Resolver program (Comcast joined Firefox's Trusted Recursive Resolver program) — the same company fighting encrypted DNS ended up operating its trusted resolver.
First-order effects
- If Google and Mozilla ship encrypted DNS by default, Comcast and other ISPs lose real-time visibility into which domains their subscribers query — the raw material for ad targeting and network management decisions.
- Google and Mozilla now face congressional scrutiny rather than just standards-body debate, with lawmakers hearing directly from ISPs that the change is framed as a consumer-harm issue.
Second-order effects
- Browser vendors gain leverage over ISPs: the Trusted Recursive Resolver outcome shows the practical settlement is not losing DNS entirely but competing to be the designated resolver browsers trust — a new gatekeeping role Comcast moved to claim first.
- The episode feeds an established playbook — US telecoms had already lobbied to stall dozens of state-level bills restricting ISP data sales — so expect encrypted-DNS opposition to be folded into broader ISP privacy-lobbying efforts in Washington.
Third-order effects
- Control of DNS metadata shifts structurally from network operators to browser makers and a small set of approved recursive resolvers, making the browser — not the broadband pipe — the choke point for internet visibility.
- DNS becomes recurring regulatory terrain: as earlier Sony-leak reporting showed Hollywood pursuing SOPA-style DNS blocking under existing law, whoever controls resolution controls both surveillance and censorship capability, guaranteeing future fights over who that controller is.
The trend: Encrypted DNS is transferring lookup-level visibility of internet users from ISPs to browser vendors and trusted resolver operators, with lobbying and partnership programs — not standards bodies — deciding the winners.
