They're just eager to make money. Both examples I gave were meant to
illustrate how totally unrealistic the "solutions" that vendors were
presenting to power companies were. And while I would trust BT to provide
internet and phone service, I sure wouldn't use them to run a smart-meter PKI.
In fact a PKI is about the last thing I'd use for smart meters ("and now you
have two problems"). For ready-made off-the-shelf solutions, LoRa would be a
pretty good start in that area.
