Sonic the Hedgehog, the wind, and why I don't want him to be electrokinetic.

(NOTE: please see the pinned comment for a few ammendments after watching) (video creator goes by she/her) Sonic being "like the wind" is sort of a buzzword that gets thrown around in discussion of the character. But what does that really symbolize, and where did it come from? And why are people so opposed to Sonic having electric powers? Why am I asking so many questions when I know the answers are just in the video?
