Although perhaps the RIAA did "win" the case and took down
youtube-dl from Github, the wonderful Streisand Effect made a pyrrhic victory out of it.

People will not be silenced by corporations, that's for sure. Now we need to work the other side: how do we switch away from a culture that worships big corporations to one where our culture gets made by the people and for the people? That's the key question. And the answer will essentially disrupt any influence the RIAA and MPAA might have on the media.
