"I wouldn’t do it every year, because I would probably collapse from exhaustion, but I’m grateful to have been able to contribute to such a project."
Why should the comment be pinned when it doesn't even grasp that the blog post isn't advocating, at all, that people should be in high-growth sprint mode 24/7/365?
I've met hundreds of co-workers and literally none of them has ever advocated for an unbalanced work-life balance, except in the case of over-balancing towards life (that is, neglecting very reasonable duties at work, that are relied upon by others).
I've also read hundreds of thousands of HN comments, and very, very few of them advocate for a bad work-life balance or spending all of your time and energy at your job, being vastly outnumbered by comments calling for balance.
I don't see any evidence that "it’s so easy to think you must always be like that, when reading articles like this" - especially because only someone lacking basic critical thinking skills will think that a description of what something is, is advocating for doing that thing.
