Probably because you did not show a good will effort to clean up your act. At least you do not tell us what were the contents of these reconsideration requests. For all we know it was: "Reconsider me!"
From your previous post I gather that you were heavily annoyed with the unnatural links actions and warnings. Instead of cleaning up your act for Google you focused on a suggested unnatural link to claim it was all BS.

I do think that the people at Google notice a prominent post on HackerNews. But I do not think that they manually removed a spam penalty to avoid bad publicity. If anything: allowing spammy sites in the index without even a slap on the wrist is not good for publicity at all (and very visible to the users). I think the pre-set penalty period was over, or a recrawl found a cleaner site.

Google has more power over their search engine index than you do. You are free to do whatever you want to do with your website.
I do have a question: The DuckDuckGo widget you had on your site (now changed to a general link), was that an official widget? Did money exchange hands for placing such a widget/link on every page of your site? I am wondering why a site-wide link to a commercial page is not 'nofollow'-ed, and if that may have brought you unwanted quality guidelines attention.
