"Marshall Erwin is Mozilla's senior director of trust and security and a proponent of the "dough" school of pronunciation. From Mozilla's perspective, the move to DoH is quite simple: it provides users with greater privacy and security.
"The internet's business model is broken," he told CircleID. "Websites engage in pervasive tracking and DoH safeguards users from that tracking; it protects them from ISPs that may try to collect and monetize user data."
Erwin points out that in the US, ISPs specifically — and successfully — lobbied to be released from new rules that would have prevented them from selling or sharing user data and gives several examples where user data has already been monetized. He also notes that ISPs' privacy policies are often "opaque.""
