I posted it on HN as I liked the points in the article. The points in the post are reasonable provided there's fair equity for the employees (which I believe is disclosed prior to joining - I have no knowledge about dilution, preference etc). I also agree with the commenters on HN that it doesn't make much sense when there's no equity.
But there are too many comments making the same/similar point.
I personally find what Alex is doing is inspiring, running a 200 person company (ref: article) at 23 is remarkable. I also applaud his courage to publicly share what he thought was best advice.
I might get downvoted for this but I couldn't not say this.
