> recent news of other tech companies making their employees work nights and weekends

Are there any companies aside from Twitter that would fall under this? Because that's the only one I've seen mentioned in the news that way, but you make it sound like there are plenty others. So I was curious if I simply missed something.

Startups. If they do the math and the trendline doesn't seem good, they'll make their teams go through a grind before layoffs. It's not necessarily to eke out a bit of productivity, per se, but they're essentially throwing hail marys in the hope that something will happen.

Of course, when it inevitably doesn't they axe a few and the rest go back to work.

Fair, I agree. For SV startups though, "working day and night" seems to be a fairly common scenario, not specific to these past few months.
