I basically agree except isn't this making fun of how self-important and pointlessly grim silicon valley VCs are? That is, it's the VCs themselves who would compare their own lives to communist oppression. The joke is actually comparing them.
I mean, per your repulsive hypothetical parody...if the person choosing jobs is your prototypical TC-obsessed, Blind-posting solipsistic narcissist tech bro, and the joke is that this archetype can't tell the difference between choosing a FAANG offer and choosing a child...that would be an effective way of making fun of that person, I think.
If your point is that silicon valley and the people in it are too vapid and socially irrelevant to be credibly parodied that way...that's fair, I guess, but also this is hacker news? If anyone is going to be interested in making fun of these people and institutions, it's us.
