The questions raised in the advertising are pretty good ones. If the city bungles the fibre network and loses a lot of money, you'll be forced to pay for it in taxes. If Comcast fucks up and their costs go out of control, you at least have a choice to opt out. As much as I don't like Comcast and AT&T, I have no faith in government to be an ISP.
Opting out means living without internet access for several years. Is that a realistic option?
I'd advise Slashdot readers to take their typical tack, and not read the linked articles. They are crap. However (again, much like Slashdot), the comments can be enlightening.
What I'm seeing there is:
d) Norway's power grid is so dirty that it is fooling the cables. That's the issue, near as I can tell.
The power grid is not dirty, but uses a different system with no neutral wire and the voltage will therefore be floating with respect to earth. Tesla cables detect this as an earth-fault and disconnect.
