> There is no way to have a web-document-embedded map that can usefully show a user things near their device's location without leaking that location to any entity with access to execute JavaScript in the context of that document. So disable JavaScript. A web-document-embedded map in a browser which doesn't execute JavaScript wouldn't leak user location. This isn't an argument against a map element; it's an argument against JavaScript. Which is fine with me: I think that JavaScript is the drug-resistant syphilis of the web. It's been an unmitigated disaster for privacy & security.
