For us to come around and examine/judge her as if she was a brainwashed fool in a startup cult makes no sense.

First, she chose to work there. She was not forced to. She has agency; she could leave at any time.

Secondly, the discussion is about work culture. It's not that she painted the work culture as toxic; she painted the work culture as inviting, meaningful, and something that helped her grow, despite the long hours. Surely something can be gleaned from that.

Thirdly, this is a startup culture. You can't choose to work in a high-paced kitchen, and complain about the heat. If you can't take the heat, leave. It is the company's problem to find someone to replace you and your value; just like you can't blame the world to change and fit you (as you must make the change to yourself), you can't blame the company to adjust around your style. Companies are commercial ventures; they have different goals and expectations than the individuals working for them.
