The dry contact I'm talking about is totally opt-in. It's a physical contact that is not used by default. You can, if you want, wire it to a power line on which you can plug a subset of your appliances. So the surface attack of this feature is that an hacker could stop you water boiler to heat or your car to charge, but you'd just have to plug them to the rest of your (still working) network. And yes, the electricity provider could probably switch off your provisioning remotely. But that's not a novelty. That was always possible. Now it can be done safely. And I'd like to add that the Linky is NOT connected to the internet. It's connected to the electricity provider network so you need to control the electricity provider in order to hack the meter. But at this point, if you gain control of the network, there is no interest in hacking the meters.
