      Lobby them to stop supporting interception via local certificate store for HPKP or at least add a way to opt-out.

      in principal I support that, yet I see little chances of succeeding with it.

      however given latest events and the sheer scale of mitm fuckups: maybe things change.

      Not every OS uses the desktop security model and getting the user to install a cert shouldn't break HPKP.

      Desktop security model as in lack of a security model. Also see https://android-developers.googleblog.com/2016/07/changes-to-trusted-certificate.html ….

      what's the solution for enterprise environments here?

      Not making their company less secure by intercepting TLS to try enumerating badness while breaking security.

      Wouldn't that mean internal sites secured by the enterprise CA would show as untrusted though?

      Not if the enterprise CA is just for a domain the enterprise owns rather than for *.

          Good point, but if the browser distrusts all added CA then it doesn't matter what they're for.
