That's fine by me. IMO, Reddit (as an example) was a great site, until it became popular and the subject material moved to the lowest common denominator. HN would be ruined too if/when you can get away with posts that do not stay within the topics/style that the community was built up from (I would figure that's why politics/sports are explicitly disallowed, and I am happy that such topics are kept off here)
If programmers.SE is supposed to be a site for "professional programmers interested in conceptual questions about software development" and this question doesn't fit that description, turf it. Like I'd expect you to turf "Who are you voting for in the upcoming presidential elections?", no matter how popular that would be.
Here's that same false dichotomy again that was in the last StackExchange thread.
Listen, it's not a choice between "Let the moderators run wild" and "let the userbase run wild". It never has been. Those are the two silly extremes in an entire spectrum of possible policy choices.
StackExchange sucks because the moderation is too heavy.
r/programming sucks because the moderation is too light.
HN is somewhere in the middle but trending towards SE (if the number of good comments which were hellbanned are any indication)
