  That's an amazing name.

    I think the name may have been coined in this HN thread: https://news.ycombinator.com/item?id=6146279 https://news.ycombinator.com/item?id=6146279 around August 2nd, 2013. Google shows some uses before hand[1], but Wayback Machine does not corroborate. I think Google is using the self-reported page date and pages dynamically update with "latest news' content.

  It partially matches what he's talking about, but it's still a trinary choice. 1> Don't tether 2> Get only power 3> Give away the keys to the castle

    FYI it's "ternary".

    2> Get only power Not really. the USB charging protocol requires data pins for chargers to communicate with the device about how much current it can draw. Suppose the data pins are left open, a compliant device can only draw <100mA, which is not even enough power to keep device from draining battery. Even if the data pins are shorted, I don't think it works with most apple devices, which use a different non-standard protocol.
