I'm surprised by the amount of salt (for lack of a better word in my vocabulary) in the comments. I've worked at a Canadian start up. It was not a unicorn, but you were expected to work long hours, be a "10xer", always be responsive, and put in hours on the weekend. Those expectations were never made explicit, but the company had a lot of churn for those who didn't "fit the culture" or acquiesce to the cult of person…
It's classic, "I know more than you" mentality, where the author believes the people who buy into the culture are being duped, and he's the only one who can see clearly.
I'm so sick of being told to be less optimistic and positive about the company I work for, because my optimism is just me subscribing to the "cult". It reeks of that classic teenage "it's cool to hate/dislike/criticize stuff" attitude that I'd expect my colleagues to have grown out of by now.
