EDIT: Thank you for your response, dang. Hacker News is a special place, which is why we have responded so strongly to today's events - I apologize if the tone above came off as less-than-civil. I (and it seems, many others) look forward to hearing more about the 'dupe' article others have linked to below. It was only upon seeing the article marked as a dupe after seeing the previous flagged out of existence that it began to feel like more than just a user-initiated action, so I am sure further information on the mod-initiated actions will put these fears to rest.
However, in this particular case, I don't think it should be flagged unless the comment sections becomes unmanageable. It may be a political topic but it is seen from a technical angle, and indeed, a lot of the comments are technical in nature: the effect of different options, different engines, alternative wording, etc...
What I think is interesting is how artificial the censorship looks. If I see no results for such a simple phrase, I know something fishy is going on and that would encourage me to carry on.
Saying/posting something which quickly gets flagged into oblivion is freedom of speech working as intended. As is subsequent posts overcoming a flagging brigade...
