My interpretation of your comment was that there was some (not insignificant size) group of people who would be unable to view this document due to some inherent limitation of whatever platform they're using to access the Internet (e.g., some mobile phone OS that can't open PDFs or something similar).
If I'm understanding correctly, however, your complaint is either that 1) nobody has provided you with an application to render PDFs on an 80x25 dumb terminal screen or 2) this document wasn't created in the format that you prefer.
When you make a conscious decision to not utilize a "GUI DESKTOP" -- like >99.9% of the rest of the world -- you must be prepared to accept such inconveniences and/or find alternatives that meet your needs. The rest of the world has no burden or obligation to cater to your preferences.
(FWIW, in an earlier comment, I posted instructions for converting this PDF to both text and HTML as well as performing the conversion myself and making available those versions of this document. You're welcome.)
