Final answer:
The author uses satire to mock man's inability to freely express himself.
Step-by-step explanation:
The author uses satire in this excerpt to mock man's inability to freely express himself. The excerpt depicts a man who has been underground, living in the cracks and forgotten, but has now found his voice through these songs. By describing the songs as 'ballads of paranoia and disconnection' and contrasting the man's lack of online presence with society's obsession with data and technology, the author is satirizing the idea that true expression is only valid when it conforms to societal norms and technological standards.
