> Isn't music better for the fact that every artist can draw their own line?

I am not at all making the argument that it isn't.

Rather I am trying to get at the idea that the "revolutionises the guitar" coverage framing that accompanies developments like this usually elides questions about musicality.

> Counterargument: does someone play the Linnstrument? Do they make good music with it?

I have never actually heard such a player myself.

I think everybody agrees that news articles tend towards hyperbole, often to the point of being silly to anyone who knows topic well. See also: e.g. news coverage of every scientific paper ever.

The inventor's site is much more reasonable (while still, IMO, marketing the product effectively): "A New Way to Play Guitar."
