My guess is this is being called out because it's symptomatic of a toxic valley culture that clearly values workaholism, to the detriment of people's mental and physical health.

Couple that with a broader obsession in the US corporate workplace for increased productivity at all costs, and I can see why people would see this as beyond the pale.

So, yes, taken as a single point, you're right, simply don't apply. As part of a larger trend in tech workplaces, it's a worrying symptom of a deeper dysfunction.
