Actually, both Sci-Hub and LibGen are mentioned in the article. Perhaps your ctrl+f failed because the page only loads the next section when you scroll down near the bottom of the page.
Exactly that happened.
But I think it's ironic for an article about open access to make itself essentially unprintable in this way. It's too long for me to read on the screen. A "page of HTML" would be demonstrably superior for that purpose.
