Use case is to copy file over slow net, but the previous version is already there, so one can save time by only sending changed parts of the file.
Not to be confused with USB CDC ("communications device class"), an USB device protocol used to present serial ports and network cards. It can also be used to transfer files, the old PC-to-PC cables used it by implementing two network cards connected to each other.
Instead with CDC the block boundaries are define by the content, so an insertion doesn’t change the block boundary, so it can tell the subsequent blocks are unchanged. I haven’t read the CDC paper but I’m guessing they just use some probabilistic hash function to define certain strings as block boundaries.

...which is more important / needed than ever. I encourage every who asks to get my music from bit torrent instead of spotify.

I'm not above piracy if there's no DRM free option (or if the music is very old or the artist is long dead), but I still believe in supporting artists who actively support freedom.
