With a pdf I don't have to update my PDF reader multiple times per month just to be able to read text.

A PDF is a text document that includes all the text, images, etc within it in the state you are going to perceive them. That web page is just barely even a document. None of it's contents are natively within it, it all requires executing remote code which pulls down more remote code to run just to get the actual text and images to display... which they don't in my browser. I just see an index with links that don't work and the the "Contributions" which for some reason was actually included as text.

Even as the web goes up it's own asshole in terms of recursive serial loading of javascript/json/whatever from unrelated domains and abandons all backwards compatibility, PDF, as a document, remains readable. I wish the web was still hyperlinked documents. The "application" web sucks for accessibility.
