The technological complexity of rendering and reading a website is weighted towards the reader. They need an advanced device, running some of the most complex pieces of software in the world, that can only be made by a handful of companies. Without that device and without one of those three main browser engines, then as far as the reader is concerned the web poofs out of existence.

The technological complexity of print, on the other hand, lies entirely on the production side. Once books are printed, you could pile a bunch of them in a wheelbarrow, stroll with them over a border under the cover of darkness, and the only thing the recipients need to provide to experience their message are literacy, their eyes, and however much lighting they need to see the page.
