You are correct. You can also look at it as if I am going to unbundle, why would I need a cord? We (essentially) have a pipe from the internet to our TVs now, so just use that cord for the individual things you want. Maybe the author has that perspective, even if the terminology is incorrect.

You're right. Added this footnote (http://stratechery.com/2013/the-cord-cutting-fantasy/#footno...):

Update: It’s been pointed out, correctly, that I’m talking about unbundling, not cord-cutting. That’s technically correct. However, I think folks who talk about cord-cutting still want the same content. That’s the fantasy I’m referring too. Still, I regret the imprecision ↩

Good point since most cord cut viewing still happens on bundlers (Netflix, Hulu, amazon prime, pirate bay).
