I suspect that the author has read Derrida. He's obsessing on the meaning of a word and following semi-random threads trying to deconstruct it. That's classic Derrida. That approach doesn't solve any problems, but it's a useful way to generate papers. If you read some Derrida, you too can learn to generate blithering of that type.

As for yuppies vs. hackers, it helps to go back further, to understand how hippies morphed into yuppies. Hippies were mostly self-indulgent types who spouted bogus philosophy to justify their existence. Yuppies are mostly self-indulgent types who spout bogus philosophy to justify their existence. Stewart Brand, of Whole Earth Catalog fame, led the transition from hippie to yuppie, from the commune to the "lifestyle industry", from growing your own food to Whole Foods.

What happened to the hacker ethos was the absorption of computing into the advertising industry. The hacker ethos survived the Microsoft era, but not the Google era. Microsoft was about tools, which was consistent with the hacker ethos. Google is about ad clicks, and its success created a whole industry focused on ads and user exploitation, not tools for user empowerment. That's what destroyed hacker culture.
