Huh, you make a good point. I'd forgotten about the days of USB dongles that do nothing but act as challenge-response devices for audio software DRM. Which makes me wonder, will all those now-legacy iLok USB-A DRM dongles still work with the USB-C to USB-A cables? Or will the iLok DRM detect the cables as a man-in-the-middle cracking attempt?

Nor does Youtube have any tubes.

Words change, but technical jargon changes faster than most.

dongle: "a small device that plugs into a computer and serves as an adapter or as a security measure to enable the use of certain software" http://www.merriam-webster.com/dictionary/dongle

It sounds like you're using a different definition of "dongle" than most people?
