You can always find reasons why something has to be a certain way. But at the end of the day, you can't expect to attract and retain curious hackers/entrepreneurs in this way. The author presumably spent some time compiling the original story, the math symbols and graphs are quite nice for instance, just to have it removed without explanation. It's not a very good way to treat people.
Does it matter? The author seems representative of exactly the type of users you want in a community like this. Long standing user account, high karma, produces decent comments and great content (the visualizations in the Swype article is another example [0]) and even puts HN comments on the blog. Whatever mechanism that ends up discouraging people like this in favor of trigger happy flaggers is broken. Fortunately for the community the author didn't go "fuck it", but instead wrote another sensible blog post which makes them an even better community member.
