I'm not commenting on whether or not the above is correct according to the decision, but in response to it, you would then be grouping email with medical records, in a sense. Yes, a third party has access to them, obviously. But a warrant will be required to look at them. At least, I think. Interesting to ponder on whether or not we really regard our emails so highly, though?

This doesn't seem terribly new or revolutionary... Here in SE Michigan we've had a "little amber light" in the box out back connected to the electric supply for the A/C for at least 10 years. During the summer, during peak hours when all of SE Michigan runs their air at once, they shut off A/C units for a couple of hours randomly to avoid brown/black outs.
