Well in this case I meant closer to a hub, but something that converts the USB-C ports on the mac to other ports, including USB-A for the flash drive.
I left that at home, so I was unable to plug the flash drive in.
Dongle itself is a kinda broad catch-all term https://en.m.wikipedia.org/wiki/Dongle
Yep, that's specifically the meaning :)
Golden = Made of gold
Gilded = Covered in a thin layer of gold
The gold and the thin layer was the 1%-ers, with rampant corruption and harsh conditions for everyone else.
