It was Fi, yes (I have the assembled phone stand on my desk). And the Lego* pack did include a short USB-A to USB-C cord. The Nexus 6p came with a c-to-c and a ludicrously short (like, 6") a-c cord, basically only useful to plug into a laptop.
C cords aren't cheap yet. I mean, they're much cheaper than lightening, but still much more expensive than A. More importantly, they're much more limited still: monoprice-really, the barometer for these sorts of things- doesn't yet have the 8'+ length cords with C connectors that they have in abundance for A, at a few bucks a pop. That will happen, and soon, because it's USB. Comparing the pricing to Lightening is just silly: C prices are high because it's new and manufacturers haven't adjusted yet. Lightening prices will stay high for artificial reasons; C will be priced like A very soon.
(*'Lego' like 'band-aid' or 'q-tip', of course. Or 'Coke' if you're dumb)
