In fact, reading the essay from beginning to end, it's difficult to pinpoint a specific complaint; the cult mentality, the intentionally-skewed work-life balance, the flare-ups of self-awareness amidst lingering self-doubt identified as warning signs and symptoms are the tradeoffs of a lifestyle that everyone in tech self-selects. What, then, is the abuse here, the toxicity, when participation in this environment is a labor transaction?
There are numerous instances of awful, toxic behavior that has occurred in the field of tech, and exacerbated by this environment that could have been called out position this essay against behaviors that are abhorrent and should never be tolerated. But conjecturing an equivalence between a driven, but self-selecting labor environment and the plight of marginalized groups is a stretch, but the writing suggests that that link is self-evident to their target audience. If that's true, the conversation has already lost its nuance, and can't be refuted without collateral damage, making it a rhetorical trap.
