Emacs is, amusingly, a lighter client than most browsers nowadays.

On point, a browser can not remember ifa notebook. Just parse the json. It can also parse text/plain. So, could show the org document without styling. The org document is actually readable. Json... Not so much.

To see the notebook, you have to have a Jupyter setup somewhere.

Edit: For example, see https://raw.githubusercontent.com/taeric/taeric.github.io/ma... which is the source for http://taeric.github.io/ChangeForDollar.html Not styled, and that is a short document, so probably woudn't be that tough to read in a json document, but I'm glad I don't have to.

How is a notebook without proper software to handle it in any way more useful then other structured plaintext-file? Yes, JSON can be prettyprinted in a browser, but what then? It's still a useless mess you can't work with.
