After three years, Pixel users still have to refer to a guide [0] or track down a Google Engineer's Amazon reviews [1] to find a 3rd party USB-C cable on Amazon that doesn't have the potential to fry their device [2].
If I were Apple, I'd be hesitant to jump on to USB-C, when Amazon and gas stations around the world are selling $5 cables and chargers that are so out-of-spec that they introduce the very real possibility of damaging devices that will end up at the Genius Bar for an AppleCare+ repair/replacement.
