Cory Doctorow writing for boing boing does a terrific job of explaining what DoH (Domain Name Service over Hyper Text Tranfer Protocol Secure) does, why it is important, and why those that would infringe on a human’s right to privacy are upset about Firefox baking it into their product.

The heart of the issue is that every time you punch in a website address, your computer has to go ask the Internet’s phone book for what that site’s computer address is, and that ask is very easy to watch for by your Internet service provider, (which they then monetize) or your federal government’s growing security state, or even used in nation versus nation cyberwarfare. DoH makes all of that much harder. Honest, moral individuals and organizations do not mind that Internet use becomes more secure and more private, only those that stand to benefit from being able to surveil all.
