This story is about an author deciding to remove an article that was posted (and upvoted!) to HN multiple times.

I'd say it was good content and personally liked the article.

In addition this story shows that 'sexism' (think PyCon etc.) is not easy to identify and no objective rules seems to be agreeable enough. For me, this article wasn't even remotely sexist and even if the author himself got convinced, I fail to see a reason to take it down and cannot see anything offending about it.

In fact, I discussed that very article with my own wife multiple times.

no. This is a story about an author succumbing to pressure to remove an article 9 years after it was written.

Ah, OK, apparently you're right about the 9 years after it was written. Do you have anything to back up the "succumbing to pressure" bit? It sounds pretty consensual from the text.
